Volumetric Lightmap Sublevel Transform Fails

My team and I are attempting to create a procedural dungeon system. To preserve that sweet sweet UE4 lighting, we want to spawn sublevels with their lighting baked in.

At this time this seems largely impossible, because upon streaming sublevels, volumetric lightmaps do not copy the transformation of the newly created level, and only a single volumetric lightmap is instantiated in the environment at a time. This is prohibitive to attempts at high quality procedural environments, like a dungeon crawler composed of handmade rooms. See for yourself:

I’ll add that I’m not alone. See [here][2] and [here][3]
