Unreal 5 Question: Can you expand / add to a level thats world partitioned?

Hey everyone, I’m fairly new to game dev / Unreal 5 in general, but my question is can I start with a relatively small world partitioned map and slowly add to it since im not exactly sure how big I want the game to be in the end? What is the best way to go about doing that / how do I add new landscape chunks to a map thats already been partitioned without the “Levels” tab?
