Seasons / Episode Lists

We should bring in the capability from V2 to add individual Seasons / Episodes to lists.

In V3, we can add Shows and Films to lists. However, many people maintain canon-based lists that would require individual seasons/episodes of shows to be added to lists.

For example, see the MCU. If you want to create a list that is timeline accurate, you would need to place individual seasons and episodes into a list. The current process would only contain the show, for example, but not the nuance of certain episodes that take place before/after films.
