Thats a feature I would love to see on CLRMamePro & i'm sure others too. I would also like to see a feature where you could remove non working games & mechanical stuff & stuff that requires other stuff to make them work.
I never have understood why Mame includes non working games as really the people who want the non working roms are the people that are trying to get them working, I do think though the more people that have the non working roms means that theres less chance of the hardwork that went into creating the roms in the first place see them not getting lost.
PS I have tried both those sites & I can't find a build that just includes the arcade games. If you do find a build please point me in the right direction.
