How to get a better material list

[JC8124]

I’m looking for help refining my material takeoffs. Currently, the software generates a general list that isn't field-ready. For example, it lists 2x6s at impossible lengths (like 53') rather than breaking them down into standard vendor lengths based on joist and rafter spans.

Additionally, my last takeoff was short on stud counts and had inaccurate measurements. Does anyone know how to adjust the settings so the material list automatically breaks at the joists and reflects realistic ordering lengths? I’d really like to improve the accuracy of my lists—any advice would be greatly appreciated!
