Is there a way to treat an Assembly as a Part in BOMs?

As an example, if I have an assembly with the following:

Gearmotor.sldasm consists of Motor.sldasm and Gearhead.sldprt and Fastener.sldprt. Motor.sldasm consists of Shaft.sldprt, Rotor.sldprt, etc.

I typically like configuring my BOMs to display parts only. This would mean for the Gearmotor.sldasm, my BOM would also list the subparts inside of Motor.sldasm.

Is there a way to prevent the BOM from displaying subparts of assemblies?

I know I can save the assembly as a part, but that can create other complications.
