Mass Renaming of Test Cases — Any Trick for This?

Hi,

I frequently run into situations where I suddenly find I have dozens of test cases in a test suite that I need to rename all at the same time. I realize that there is no way to mass-rename from the main interface, but only one test case at a time.

Is there a way people found to do this kind of thing? I imagine if I went into the project file, which is xml, I could possibly do something from a text editor, but I wanted to see if anyone else has found a reasonable way to address this. Thanks for any response.
