Is there a way to replace source OBJ/FBX after I have imported the mesh uncombined?

Hi. When we import static meshes into the scene there’s an option to combine the meshes or not to.
The thing is I can easily swap the objs from the project window with “Combine meshes” on, as I keep modelling. But if I import the obj with “Combine Meshes” off, it imports everything separately (I can texture them individually) but then I lose the option to update them all in a single click as opposed to importing mesh with “Combine mesh” on.

Is there a workaround, so that I can import the obj/fbx uncombined into Unreal, but still can replace the models as I keep updating them throughout my modelling process?
