2 configurations same list parts.

[leggera]

Good evening,

I modeled 1 semisphere with 2 configurations as in the company we go to buy 2 un perforated semispheres and then we feed them in 2 different ways.
As a result in my list the same number part 2 times with quantity 1.
Is there a possibility to make only 1 part number appear with quantity 2 ? or as if it only saw the primary state ?

I've done a little passet, or you're pulling the fuction:
I managed to shorten the two configurations, but at this point if we want to be dotty
I would like to understand how to make the sum of the two masses that would be 6.60 and 6.57 kg or the two perforated semispheres.
or make him put the mass of the primary model state.
