There has GOT to be someone out there who can point me in the right direction!!!

I am designing a trailer and there are 3 or 4 different types of tubing being used. All of the tubes must be bent at the same position to create and angled slope at the back. I am able to do this without issue.....until I get to my cut list. Solidworks appears to be creating a bounding box to populate these dimensions.

What I need is to be able to provide the guys the correct length of tube prior to bending. How can I achieve this! I obviously do not want to manipulate the cut list properties manually because when I create another part file in a different length, I need to then go into each tube again to manipulate the lengths to accommodate the new trailer length.

Any help on this issue would be greatly appreciated!!
