Can I build Addressables from other Unity project?

I'm trying to keep my main project as lean as possible. The more graphic assets I add, the more my project build time goes up, re-import times go up, etc.

My idea is this: Make a new separate project for each environment, then export an Addressables Group from there and load it into the main project at runtime.

So far so good, but what's the best way to actually make that happen?
Can I even export individual Groups and then combine them with other Groups exported from different projects?
Has anyone tried something like this before?
