Add “Track is in Playlist” as a filter criteria so you can use smart playlists to combine several dumb (or smart) playlists in one automaticaly updating smart playlist.
And add “is in Collection” while you´re at it, for the same reason!
There’s already an existing feature suggestion discussing the option to filter by tracks in playlists. For that part I suggest you comment/vote in that existing thread in order to avoid distracting/dispersing votes.
You can already filter for items in collections and make that a criteria for smart playlists/collections.
Unless I’m missing something, I’ll close this thread as a duplicate (or already implemented features).
Since that thread is from 2017 I think it´s time to start a new topic as a reminder, or just give up hope, since the Plex devs obiously doesn´t care about their customers wishes…
That’s not how the feature suggestion category works.
2022 clean-up:
- filter for playlist membership → duplicate
- filter for collection membership → implemented
