Efficient Packaging

I wasn’t sure what category this post best fits however I will detail the question below.

I have a game in development and so far I am able to build it without any real issue.

My game is open-world. When I package the project, I absolutely HAVE to load each and all useable streaming levels in the world composition. If I don’t, the nav mesh is never built and during gameplay all of my AI in the world wont move (because the nav mesh isn’t built).

I currently have my nav mesh set to only build around invokers so that it won’t have to build a nav mesh throughout the world.

All in all… I’m wondering if there is a better way to do this? When I package my project, I am forced to load ALL of the streaming levels before I package the project.

Any advice?
