[feature request] A different kind of smart playlist.

I have a library in plex that consists of recently aired seasons of TV shows. What I would love, is if I could make a smart playlist that consists of the first unwatched episode from each season. For example, it would take the first, unwatched episode of Man in the High Castle, The Expanse, Black Sails, and Bosch, and make a playlist. Once I watch the episode of Man in the High Castle, it would remove that episode from the playlist, then add the next unwatched episode of that show to the bottom of the playlist. It would keep repeating this cycle until I watch all the episodes. If I add a new show to the library, the playlist would add the first episode of that show to the bottom of the playlist.

Brilliant idea!

This feature is definitely needed
