No. PUP SSF is hard coded to use the ballroll0.wav to ballroll5.wav files. The names can't be changed (and can't be changed in script). You can however replace the sound files with your own ball rolling as long as you use the same name and they are still wav files. That said, if you make changes to any sound files (or add new ones) to your own FP_PUP_SSF folder, don't include that folder with the same name in any tables you upload. Rename that folder and change your table script to use that same name to match to prevent you from replacing the original FP_PUP_SSF files that are used by other tables.
