How do I get streamed instance level built light maps showing in persistent level?

I’ve been through the forums on this topic but I’ve not found a way to solve it yet. I have an open world persistent level (similar to Kite Demo). This uses world compilation with landscape tiles and layers all working fine. I use dynamic only lighting at this level. I then have houses that stream onto the level at runtime via blueprints to have them appear at a pre-described transform. These house levels have been baked to a high visual quality individually as separate maps. However, when streaming them in they appear with no baked lighting and show up with preview worded all over them and understandably very shadowed. What is the best way to get the original baked lighting to appear in the world level across multiple properties (sub-levels)? I am trying to get the gameplay where there is open world freedom but the player can then enter a property that is rendered to an ArchViz quality in the smoothest possible way. Any recommendations? I need a solution that would scale to 100s of houses in the one persistent world map.

you can’t use streaming in that way.

It requires the same lightning setup for persistent and streamed levels.
