Hi @james ,
now we are able to create our own collections.
It would be cool, if we could create own collections withing custom collections.
There are several examples, where this would make sense:
Ironman trilogy, Thor Trilogy etc. withing an own MCU collection
Lion King trilogy within a Disney collection
Star Wars 1-3, 4-6, 7-9 in a Star Wars Collection (that also contains the Solo movies)
Home Alone in a Christmas collection
