Add new entry in PinMAME for "muted" popper-roms?

[Dazz]

Some of the new Pup_packs for Pinup Popper use a muted ROM so music for the game is generated via the PuP Pack.  They include a modified version of the ROM that has had the music removed/muted.  As of right now you have to replace the original ROM with the muted one, using the same name.  I'm afraid that if some of these muted ROMs get out into the public and mixed into ROM packs; that eventually ROM sets may be corrupted.  Would it be possible to have new entries added into PinMAME to accommodate for MUTED ROMs?  Perhaps just a new name entry like we've done for colored ROMs?   Or would it be possible to add a MUTE option in PinMAME itself so it can mute the music from the ROM?  This way people can just select the option for that specific ROM to mute the music.
