As a rule, in our BOM the QTY (quantity) equals how many of a part/assembly are included/inserted in an assembly.

We've recently come across a couple situations where we need to  override that number for a particular item.

As an example, we have Screw X and we want the quantity to equal 100.

Is there a way to get a manually entered QTY to show in the BOM for only one specific item when the BOM has many lines?

For all the other items I want the QTY to equal the total in the assembly.

It's like I need only 1 line in my BOM to read a Custom Property for this one item.

If this do-able?

Is there a different methodology for accomplishing this?

I really want to avoid inserting 100 instances of this one screw in my top assembly, even if it's a pattern. (If possible)

Solidworks 2015 (if that matters)
