FFMPEG Core - Is it possible to use a playlist?

Is there any way to make it so I can easily select different episodes, movies, etc from ‘within’ retroarch? I don’t think there’s anything like .m3u support for the core (right?), but I know I’ve heard people mention they have playlists setup for their games somehow.

I’m used to using a frontend to launch my games, so this is kind of a new area for me here.
