Parts on BoM with no model...is it possible?

I use SW for architectural drawings.  I want to be able to have items show on my BoM's without having to model them  (i.e. vapor barrier, insulation, pipe strapping) Is there a way to do this? 

I know that I can manually add line items onto the Bom, but would prefer if I could attach to the model.

Thanks,

Colleen
