AutoCAD Inventor :: Duplicating Vault Project And Renaming Every Related File

I want to duplicate & then rename a project I have stored on my vault computer, However I am experiencing many difficulties.

There are probably around 1000 + files in this project-multiple assemblies/drawings & parts. Initially i did a Pack & Go of the Project to my desktop. I then took my first top level drawings & using Design Assistant renamed all the reference parts and assemblies related too it. This worked fine, albeit a very long time to rename all the files.

The problem is that i have say 50 drawing files, some contain similar assemblies/part files which will have already been rename in the first top level drawing & some container different assemblies/parts (which are not related to the first top level drawing) & will have to be renamed separately.

Is there an easier way to duplicate & rename a vault project because design assistant makes this task extremely laborious. An great tool to add would be to 'Find & Replace' a file name & apply it too all the files. Similar to the function in Microsoft Word.

I have looked into the copy design feature in vault however, you can only copy a project within a project, you cannot copy it to a completely new folder in the vault.

The other problem is, is that you can only add a prefix or suffix to every file/related part/assembly, & i would rather replace the project number rather then add the new project number to the file names. This would be a viable option if you could rename multiple files quickly, however this just stems back to the design assistant.
