Do not merge bios files into roms

As far as I can tell, there is no option when fixing a set of roms to not merge the bios files into the game roms. Can we please add a feature for this? I guess as a work around I could filter the DAT XML to remove the bios files, but that's a real pain.

Here's an example of a machine romset in my DAT that's auto generated out of mame2003-plus:

As you can see it's possible to filter out bios files based on the bios attribute within the rom element.

I'm not sure what you're asking for here. Gorom will ignore any XML attributes it does not handle including the bios attribute so it will not merge any bios files into the roms.
