2 years ago This seems like a screenshot from desktop, but the same is probably true for Android as well. For desktop it's planned by upstream to implement drag-n-drop eventually.
Having the opposite way (assigning rooms to spaces) available, is probably a good addition though. But first spaces should settle down a bit, they're still in flux, and upstream might still have own plans regarding this.
Describe the solution you'd like Quickly add a room to another space. Only way I know to do this is go the target space, find 'add existing room' Would be nice via context menu ... something like Add to Space > [submenu list of Spaces]
