Creating Multiple Skeletal meshes on vehicle Import

I’ve been following several tutorials on how to make a vehicle in blender and export/import it to UE4. Whenever they import it, it creates a single skeletal mesh with the wheels as children. Whenever I import it, it creates separate skeletal meshes/physics assets for each wheel and body. I have correctly made the wheels, children of the body in Blender before exporting. Am I doing something wrong? Is there a way to change the hierarchy even with all of these separate meshes?
