I really need your help.
I've created a new page layout in SharePoint Designer 2010 and I want to apply it to all existing pages in a site. Another thing to note, some subsites and pages use different page layouts. If possible I would like to standardize all page layouts.
I checked online and I found some methods but it seems all of them require the page layout to be "un-customized" and deployed using Visual Studio. I've developed the whole layout in SP Designer and I have no clue how to move it to Visual Studio 2010. Is there any way I can do this using Powershell commands or any other tool?
