Is it possible to import a .sat or .step file and retain the original part names?

I have exported a bunch of parts as a .sat file and imported it into SW (2018). Solidworks renames all the parts as the .sat filename [#]. Is there a file format that retains each body's/part's name?

What is the best way to import an assembly type model into Solidworks for easy manipulation?

Thank you!

Example of what I see after import:
