Customize measurements section within takeoff

Hi, I’ve built a workaround, but I’d like more control over how measurements are calculated at the takeoff level.

I use Linear with Width & Depth to represent duct runs and calculate surface area for insulation. In practice, I’m calculating wrap area based on perimeter × length (rectangular and round duct), and I’ve built that logic into my item formulas so material and labour are accurate.

The issue is at the takeoff level. Even though width and depth are defined, the takeoff still reports in linear, and the built-in “Area” measurement doesn’t reflect true wrap area. As a result, I can’t get reliable square footage totals without relying on item-level formulas.

What I’m looking for is the ability to customize how measurements are calculated at the takeoff level, specifically:

• Define a custom formula for area based on width depth and insulation thickness (e.g. perimeter × length)
• Have that calculation roll up cleanly as square footage in the takeoff

Right now the workflow works, but it’s fragmented. The takeoff doesn’t reflect the real quantities I’m actually pricing, which creates extra steps and room for error.

If measurement formulas could be customized at the takeoff level, it would make this much cleaner.
