Is it possible to prevent SharePoint 2010 from creating a folder structure when users upload files?

Question

I have a wiki library with pages and a document library which I've configured to be an assets library. How do I prevent sharepoint from creating a directory structure for file uploads?

The wiki pages are organized like so:

Root/Finance Dept/Payroll/Best_Practices.aspx

When a user uploads a file from the Best_Practices.aspx wiki page, it creates an obnoxious directory structure under the target document library:

/Root/Finance Dept/Payroll/Best_Practices/Sample_File.PDF

The issue being that Best_Practices.PDF might also apply to another area under payroll, and so it doesn't make sense for it to sit under the Best_Practices folder. Also, when files get hidden deep down in the folder structure, they tend to get missed and we end up with duplicate files because most users wont run a search.

Is there a way to prevent this without implementing content approval, or other draconian methods of enforcement?

If it isn't an asset library or the Source querystring isn't passed in, it looks like it won't create the structure. See the reflectored code below:

                string text2 = "";
                string text3 = "";
                if (sPList.IsSiteAssetsLibrary)
                {
                    text2 = base.Request.QueryString.Get("Source");
                    if (string.IsNullOrEmpty(text2))
                    {
                        this.ErrorLabel.Text = SPHttpUtility.HtmlEncode(SPResource.GetString("CouldNotUploadFile", new object[]
                        {
                            postedFile.FileName
                        }));
                        return;
                    }
                    try
                    {
                        Uri uri = new Uri(text2);
                        text2 = uri.GetComponents(UriComponents.Path, UriFormat.Unescaped);
                        text2 = "/" + text2;
                    }
                    catch (UriFormatException ex)
                    {
                        this.ErrorLabel.Text = SPHttpUtility.HtmlEncode(ex.Message);
                        return;
                    }
                    string extension = Path.GetExtension(text2);
                    if (!string.IsNullOrEmpty(extension))
                    {
                        text2 = text2.Substring(0, text2.LastIndexOf(extension, StringComparison.Ordinal));
                    }
                    text2 = base.Web.GetWebRelativeUrlFromUrl(text2);
                    text2 = sPList.RootFolderUrl + ((!string.IsNullOrEmpty(text2)) ? ("/" + text2) : string.Empty);
                    text3 = text2 + '/' + text;
                }
                else
                {
                    text3 = sPList.RootFolder.ServerRelativeUrl + '/' + text;
                }

                SPFile sPFile = null;
                SPFolder sPFolder = null;
                text2 = base.Web.GetWebRelativeUrlFromUrl(text2);
                try
                {
                    if (sPList.IsSiteAssetsLibrary && !string.IsNullOrEmpty(text2))
                    {
                        if (text2.StartsWith("/"))
                        {
                            text2 = text2.Substring(1);
                        }
                        string[] array = text2.Split(new char[]
                        {

                            {
                                text4 = text5;
                            }
                            else
                            {

                            }
                            sPFolder2 = new SPFolder(base.Web, text4);
                            if (!sPFolder2.Exists)
