How to change filename via Upload.aspx

Question

I've managed to upload a file using the code below

<a onclick="openDialog(); return false;" href="#">Open Attach File</a>
    <script type="text/javascript">
        function openDialog() {
            var options= {
                url: "<blahblahblah>/_layouts/Upload.aspx?List={blahblahblah}&RootFolder=",
                title: "Attach File",
            };
            SP.UI.ModalDialog.showModalDialog(options);
        }
    </script>

My question is how do I change the filename retroactively?

In library, take one extra column say as "test" and then check upload file. It will redirect to other page in which you got all properties in edit mode. You can change title from there.
