Question Exlcuding FBX model from bundle - use FBX from build instead

RESOLVED - Using Asset Bundles in the correct manner, creating separate bundle for the FBX instead of having it in the main build

Hi
Is this possible?
I have multiple prefab characters that all originate from a single MASTER FBX in my build.

When I build out assets bundles for any of these characters it always includes the FBX model in the bundle. The FBX 11Mb so I want to try and exclude this from the bundle and use the local FBX source in the main build.

Is there a way (dependencies or addressables maybe) such that I could bundle the prefab excluding the FBX model and have the prefabs reference their model to the FBX in the main build?

Searching around has not found me any relevant information to this specific issue.

Thnx
