Yup. P3DO just does batch renames. :D And something that helped keep me sane awhile back...you can rename the extension of your MAT files from .pz2 to .cm2 and move them to your camera libraries. I do this since I have significantly less cameras than poses. They work just the same there (or in the face and/or hand directories too) You can do that by hand, or P3DO has a plugin that renames extensions as well.
