Importing assets into Unreal 4.20 using python

After a little bit of research on UDN I found this: https://udn.unrealengine.com/questions/401847/view.html

Doesnt sound too promising as dropping parts into a blueprint manually will make us lose the scene hierarchy as it was stored in the fbx to be loaded.

But thanks for digging into that, Alex.
