scenes across multiple rooms

I’m having trouble working with scenes in multiple rooms/venues. i had scenes correctly setup for my yeelights in my office and working with alexa. Now i have added yeelights to my home (3 different rooms, defined in yeelight app and alexa). All lights are connected and working, but if i try to trigger a scene “alexa turn on normal” it is switching ALL my lights on in all my rooms and venues to that setting.

What is the correct way to interact with it so that i have voice control but it is triggering scenes for the rooms i am in?

I would hope once i establish what “night” looks like, or “dim” or "full, then i could use that in whichever room i’m in rather than naming a new scene for each room.

I am afraid you need to setup scene for each room.
