Exporting assembly as STEP file retaining tree structure and folders

Hi everyone,

I would like to export my SW assembly, including several subassemblies and parts folders to a STEP file. The STEP shall retain the hierarchy of the SW assembly.

SW exports to STEP only to a flat assembly (all parts at the same level).

The question is:

Is there a workaround with some other software?

and more fundamentally, can a STEP file have an internal assembly/subassembly structure?

Thanks a lot!
