Playlist or database based on playable character types

[soqueroeu]

Hi All!!
I intend to obtain a playlist for each system where the playable character is either a ninja or a samurai. I want to try this feature on other types as well.
How could I get a playlist of games with only ninja or samurai characters, on all systems from 8-bit onwards?

Is there a plugin that does this filtering, not necessarily in Launchbox?

Thanks!
