An option to play the first unplayed episode off a list of shows, and when it’s done, random from that list and again play the first unplayed. Either in OnDeck or possibly create a dedicated playlist of shows.
With a bit of preparation, this is already (kinda) possible.
Only the ‘random’ part doesn’t work.
