Is there a way to create a playlist that consists of a few various shows, and as those episodes are released, they are added to that playlist? Like, I have 3-5 shows that are in a playlist that my wife and I always watch, and as episodes from those shows are available, they show up on that playlist? Is this possible?
create custom filter in web app and make a playlist when filtered
I am trying to see where to do that. Where do I go to make a custom filter? This sounds exactly like what I want 
Nevermind, I found it. We’re good to go!!
The playlist created will be based on the filter and how you sort the filter
Early 2021 clean-up: implemented (custom filter -> smart playlist)
