Romcenter

If you decide to merge samples with roms and then discover that some samples are missing from the game files (zip), and then you add sample archives to the samples folder in mame, is there a way to have romcenter recognize those samples from the samples folder and add the samples to the game files?

Thanks!

Perhaps a more general question worth asking is, in the context of MAME:

If after fixing files that can be fixed and still discovering a number of non-working files, is there a mechanism for adding individual roms without just replacing the non-working files altogether? In other words, does RomCenter support fixes that involving adding new files?

Thanks!
