Importing 3D formats into DraftSight Premium

It seems like we are only able to import 3D DWG/DXF or .SAT format files into Draftsight Premium 2019.

Does anyone know if Dassault is planning to add compatibility with the common neutral formats (i.e. STEP, IGES) in future releases? Or can anyone recommend a good external software package for conversion of STEP/IGES into 3D DWG or SAT formats?
