Grouping several actions together for re-use

Hi all, I was wondering if it was possible in HE to group lots of actions together so that I can trigger them in multiple places.

Currently I have a button that turns everything off downstairs which contains lots of actions

I want to add the same actions to other routines/buttons/etc but don't want to repeat setting up each action again. Is it possible to do something like create an action group, 'Downstairs Off', which contains all those actions. Then I can call 'Downstairs Off' from multiple places?

I had thought that creating a rule with lots of actions could be run from elsewhere but I can't see where a Rule can be triggered from another app

Also, I've tried "Groups and Scenes" but Sonos doesn't show up in them.

Ah, I clearly did not look properly. It is available
