World Composition "Find Loaded Levels"

Hello,

For my setup I have a funeral home you enter from outside and an elevator both are separate levels when you go into elevator and press button to go “down” the only thing that happens is the (Funeral home level, Terrain Proxy level, and another sublevel) unloads and then the Basement loads in and Elevator doors then open to the Morgue “basement”.

If I were to save current level this would save the base persistent and only load in the funeral home again as it is defined to be loaded when start game with an array of sublevels.

Then even if I do save the currently loaded levels I would need to tell the base array not to load some levels now needing to be omitted.

What is the best course of action here? thank you.
