pack and go add a suffix

If I do a pack and go on an assembly and add a suffix to the file names, say "rev1", now all my files say rev1, as I wanted.  Now I want to do another pack and go to move my assembly to "rev2."  Is there a way to have solid works explorer remove the suffix "rev1" and add a new suffix "rev2?"

Thanks
