Extend "add to group" functionality on switches

At the moment - if I try group certain devices - the options are limited…

if I have a switch - I would find it super handy to be able to group it with any other switch - regardless of what device that other switch is in…

eg - I have multiple rooms - which each have individual outdoor lights, which light up outside that room… it would be nice for each of those rooms switches, to be able to control all those outdoor lights - regardless of if they are in 1 channel switches, or multi channel switches.

I also have rooms where I have downlights, and iFan devices - it would be nice to control all those lights as 1, regardless of which device changes the switch state, etc etc

same for my ns-panel - 1 light is indoor, one is outdoor

the use cases are endless :slight_smile:
