WTH can't a scene be recalled per space?

I think it would be great to be able to have a scene for the entire house that can be recalled room by room, by the floor, or by the house. For instance, “Off” could be recalled by a sensor for a single room, or by the floor when I go to bed, or by my alarm panel arming away for the entire house. Instead of needing “off” for each room. Or “Day” for each room.
