Collections Grouped in Collections

Is this a feature relevant to companion itself, and not a specific module?

Describe the feature

Ability to group a collection of connections/collections into another collection.

Usecases

We use one central companion "server" that everything uses satellite to connect to. We also have multiple rooms and a lot of connections due to this. We'd like the ability to organize collections into the rom they belong into, and then into sub collections of Video, Audio, Control, etc.
