Multiple Levels, Multiple Lighting Setups

Hello! I’m aware of how to work with Lightmass for one level or one scene, or a persistent level with streaming, but how can I setup multiple different levels with different times of day? Say, a Mario game with a daytime rolling hills level, and a nighttime ghost house level, both in the same game? If a directional light is placed in a level, does it only bake for that level and nothing else? What if I want to set up level streaming within those levels?

That doesn’t solve the question of having multiple levels. If my game has a volcano level with drastically different lighting than a bright and sunny rolling plains, how should that be setup? Do directional lights in one level affect another? I know the persistent level affects everything, but I’m not so sure about lights in other levels.
