Advice on aligning streamed levels?

I mean it’s as simple as it gets.

Start up open door. Door streams in random level. The problem is even if I know the entrance point(door location) there is no way to pass that to the next stream level and it’s bp. I have no way to pass that along. I need to somehow communicate that with the next bp but nothing will work and I’ve wasted like 2 weeks on this now

So what happens is the next stream level just streams in at world 0,0,0 so they all glitch inside each other. I can manually set an offset but that means I have to premake the level geometry in blender and I absolutely do not want that. Otherwise there is 0 point to doing it this way at all.
