Gene, I don't quite understand you: From my point of view, there are 2 reasons to copy a project and work on the new one:
1) if I want to freeze a project and work on a new revision. In this case, I don't mind that the project and files have the same name.I just rename the folder name.
2) If I want to start a new project, but want to use all teh system profile from an old project. The IDE enable you to start a new project and import the profile from another.
So, if you need a 3rd option, please clarify your needs.
Brgds,
