I'm attempting to set up a costing template for our shop and I'm having some difficulty. For stardard minimum-radius bends, we use a press brake, but for larger radii, we actually roll the metal, and the time/cost for that is based on how long the rolling is.

Unfortunately, I can only seem to set costs on a fixed per-bend  basis; Am I overlooking something, or is this a limitation in Solidworks' Costing?

thank you!
