One Click to join all subspaces

[JokerGermany]

Your use case

What would you like to do?

When I am in a Big Space like https://matrix.to/#/#fosdem2024:fosdem.org , i Would be able to let element join all subspaces.

Why would you like to do it?

Because rooms you joined which are in subspaces aren't sorted in the main space and it's really hard joining all the subspaces manual

How would you like to achieve it?

A Join Button by Rooms and Spaces

When the Button is clicked it asked if you want to join subspaces or subspaces and rooms.

Have you considered any alternatives?
