Continuous Playback - On a per show rule

I would like to have the option to have continuous playback at a per TV show level, instead of global.

I don’t want it to be continuous playback on the shows I watch normally, but on some cartoon TV shows for my kid I’d like it to be active.

Even if this could be done by dropping a trigger text file into the show in question I’d be happy.

Can this be done please?
