Collections across libraries

My example here is Dune I have the made for TV and the actual movies I would like to be able to add a collection across my TV and my movie library and have all the titles in one place. If there is a way please let me know but i have not found one.

You can create same-named collections in each library and they’ll show up as related content.

Here’s two examples of how this can look/work.

Matrix

Matrix collection with the main features, soundtrack and a specials movie I’ve stored in a separate library
Example 1 - Matrix

Ghost in the Shell

Ghost in the Shell collection with the animated and live action movies, linked to the related shows.

Example 2 - Ghost in the Shell

There’s an existing suggestion thread discussing an option to actually place items from different libraries into the same collection. If that’s what you’re aiming for you should comment/vote in that thread in order to help us avoid distracting or cannibalizing votes (in which case we should close this thread as a duplicate).

2023 clean-up: implemented (same-named collections showing as related media), duplicate (cross-library content within one collection)
