Consumables in an SW assembly/ BOM

By making a non geometry part in an assembly and saving within the assembly I can count for consumables in the BOM (grease, loctite, oil box of nails etc)

However when I put baloons on the assembly these parts show upas items....

How to avoid that?

I am sure thousands of SW users have to account for things like grease, loctite, oil etc in Assembly BOMs

Any ideas?
