Mark a Part so that it never appears in BOM's

Hi,

I was wondering if it was possibly to mark a part with a property or otherwise so that it would never appear in any BOM when used in an Assy?

Example, We have Mannequin models that we use to portray a scale to customers on all top level drawings, which we exclude from BOMS every time. I have been asked if it is possible to mark this part so that it doesn't ever appear on BOM's as we do not need to call up a mannequin!

Cheers

Andy
