Animation Export Issues (Master Actions)

Hello there!
I have a small problem when it comes to exporting Animations:

I am working on a game Project with animated Buildings. Each Building consists of multiple objects and needs multiple animation clips. (Idle working, Halting, Idle not working, etc.)

So I need to export Actions from blender to Unity. And i also want multiple Objects to use the same animation Clip. What I currently have to do is bake a Global Action when exporting the Building and then re-export the building for each Animation Clip I want to have.

But I’d like to just have a single file containing multiple global actions. Is there a way to make that work?
