a filter option for rom in multi emulator mode

[Aeliss]

There is something like this implemented in the future version ?
I m trying to put the amstrad system"in the box" and 50% of the games are only duplicate or next disk.

For playstation I can delete the cue file of the useless disk, and select rom by the cue.
For amiga I can rename the useless disk and use a script to load them on other drive, because I test them one by one.

But for amstrad, i have a pack with 9200 files

I think a filter option like "cd2" or an exclude list will be usefull to avoid parasit name in rom list.
