Short answer: No, there isn't any.
The closest you'd come is "Rom Organizer 1.2.1" by Richard Bannister (www.bannister.org) which renames (some) GBA but not NDS. I've been looking for a while with no luck. I don't know how you'd be able to use applescript or automator to cobble something together, but with a dat file and a way to peek into the roms, maybe something's possible there. I continue to search, if I turn up anything, I'll post the results.
I'd be happy to be wrong about this.
