I had requested this enhancement (see spr 583595) for some time. Promote option from SW to EPDM BOM.
I really hate this SPR. We use the 'hide' option for things like air cylinders, where there is a separate body and rod part but we just like the assembly to show up as a bom item.
Also, we use parts-only epdm boms, so these things don't show up at all, and will sometimes get missed when ordering things.
I complained to the PD guys at Solidworks world about this, and also recently had my VAR escalate it.
