Level with sub-levels and single lighting scenario for all of them

I have an level that represents the main street in the game. It is consisted of several sub-levels for smaller parts of the street, little park nearby and so on.

The all share same lights (sun etc.).

It all works just fine when I open the main level which has all the sub-levels together with level with lights (lighting scenario).

But when I switch to work on given sub-level, it does not have this lighting scenario, therefore it’s “all black”. But If I add the lighting scenario to it (and each other sub-level), when I later open main level it will have multiple lighting scenarios (1 per each sub-level + 1 initial one).

Is it possible to have my lighting scenario only once in final scene (the one that include all sub-levels) and still be able to see something in sub-levels (aka for them to use light level when I work inside them).
