Importing multiple DatasmithScene elements into single level


I am trying to create python script, which will setup CAD models in level according to data from database.
I can now import single model and move it as an actor with add_actor_local_transform().
I cannot however import 2 models through python, as only the last imported one is visible (also in World Outliner)
I have read, that datasmith import replaces the scene with the hierarchy of meshes from CAD object.

I could do it through Datasmith in Unreal Editor with manual control.

Any idea on how to do it through python?
Is there a way to import more than one CAD model into DatasmithScene?

best regards
