I have a chassis that has some mirrored members between the left and right side of the chassis. In the Weldment Cut List, for example two identical members are marked under the same name and it is given a quantity of 2. I have added a custom balloon with a custom name for the "child" member, but this custom name isn't then put in the Cut List, and the "parent" member still has it's name and quantity of 2.

I hope that made sense. How can I tell SolidWorks to interpret these two as unique members?
