Level Streaming without adding new map

I need an advice in loading map-chunks based on same Level. I want to load it multiple times (don’t want to create new levels in editor) and now i am using Load Level Instance blueprint function, like this:

but it causes application lag when i need to load 3-6 chunks when moving between areas.
Is there any way to load (actually copy and transform) a level on fly using blueprints?

Don’t use load level blueprint. Use level streaming volume but you still create another umap.
