Brightness Action: Select Surface by Index

[JonFStr]

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

• I believe this to be a feature for companion, not a module

Is there an existing issue for this?

Describe the feature

It would be great to have another action for setting a Surface's brightness, similar to Surface: Set by index to page, where one can select the surface by its index (including with variables).

Usecases

I am using a trigger looping over all connected Streamdecks to put them in "standby" – i.e. set them to an empty page (as shared here) – and would like to additionally dim the brightness of each streamdeck by looping over them.

Since the number and specific IDs of the connected Streamdecks may change in my setup, hardcoding their IDs is quite annoying to manage.
