Assemblies in BOM's as "Parts"

At my company we're modeling certain pieces of equipment as parts (.sldprt) and others as assemblies (.sldasm).  Anyone know of a way Solidworks will recognize the assemblies as parts (just for BOM purposes)?  We have to use "Parts only" for BOM's, so unfortunately a piece of equipment modeled as an assembly will produce multiple lines in a BOM.  But we want every piece of equipment to be one line on the BOM.  Of course equipment modeled as a part file (.sldprt) don't have this problem.   My only solution is to "convert" assemblies to parts, so every piece of equipment is a part file (one line in the BOM).

Thanks.
