Is it possible to make a bunch of smaller chunks of a level then piece them together at run time?

I have one question left, I cant seem to find a tutorial or example of someone streaming a level at a selected location in the world. Most examples seem to assume the level location never changes and the only reason to stream something is to toggle it on or off.

I don’t see anyone streaming 3 or 4 of the same hallway or room and connecting them for example.
