trim items square regardless of trimming surface orientation

I'm not sure if they are taking ideas for 2017 yet, but here's one:

     I would like to have an option within the weldment trim feature to trim items off square, regardless of the trim body/plane orientation. I'm not going to try to get my welders to cut a tiny little angle. Wouldn't be a big issue but it throws off the actual cut list lengths that I need for my parts because "LENGTH" is based on the longest total. I tried to work around it by manually entering my length but the editor will not let me change the value/expression. adding a bunch of cut-extrudes messes with my rebuild times and actual working time. Just a thought, has anyone else ever wished for this?
