Generate Playlists (or Collections) for Series and Movie combinations

[an-ghinid]

As a potential enhancement I would like to be able to have a Playlist (or Collection, whichever is more viable) that contains mixed media all together, so for example a playlist or collection like follows:

Neon Genesis Evangelion -> Entire original series, + End of Eva + Rebuilds

or similarly

Jujutsu Kaisen: JJK S1, JJK 0 (Movie), JJK S2

In which you can watch through the entire set of episodes and movies ordered by release all in the same location.

I'd definitely prefer playlists, because I like to group my movies in boxsets as collections.

I'd probably switch to collections for this if boxsets ever become their own separate sorting type in JF since I think a boxset and a collection can overlap, but don't necessarily are the same.
