Creating a forest then wrapping it into a Blueprint

Another issue I’m facing,

My method for creating an endless Camera drive, is to have 2 blocks of this jungle,
so in this method it would mean 2 instances of the level.

Then, with a box collision, when the camera (which has a collider as well) overlaps, I teleport the position forward so the whole block moves.

I don’t see an option though to move the whole level as a whole, similar to moving a blueprint where all the meshes/lights/etc in side move as well.

Is that possible?

So I basically need to
1- have a box collision within the sub-level recognize the the camera (from the main level) has collided.
2- teleport only the relevant sublevel-instance with all its content
