How to group static meshes inside the blueprint/actor editor? /Creating an physic actor/blueprint out of multiple meshes without having it fall apart apart

As said in the title I’m trying to figure out how to build an actor out of multiple meshes I made in Blender.

When I spawn the actor in the world at runtime(with physic simulated), the actor just falls apart. I also can’t group the objects/meshes like I can in the scene/minimal default view

I couldn’t find anything working related to this question, so it would be nice if someone could help me (:
