How to package a level instance in the form of .pak files for DCL

Hey Community,
Is it possible to package a level instance in .pak files which could be streamed in our persistent level (at a particular location_ of the core game when it’s downloaded

For instance, we are trying to create a city in which the buildings are customisable. We want the buildings to be in a different level which would be streamed to the persistent level. It’s possible to package that in the same build but we are trying to transition in the form of a DLC. So each building could be in the form of level instance in .pak file which could be mounted to the core game and streamed to the persistent level

Thanks in advance
