Adding a column for 'Quantity Before Waste' & a column for 'Waste Quantity'.
Basically just needs to be the output from [Formula].
Another useful feature would be for custom properties to be calculated in the reports worksheet. So we could create our own calculated columns such as Qty before Waste and have it be rolled up into groups like the default columns.
Sometimes it's useful to calculate waste, but not useful to order that waste.
You can add any of your custom properties to your reports worksheet.
You can add Qty without waste, Order Qty, etc Qty, and then see any or all of them in your reports.
Hi, Kory is correct, you can add custom properties that have their own formulas, and when you add takeoffs or items that use these properties, and show those columns on the reports tab, the calculations show the results you would expect.
You can, yes. But it won't total when grouped by item. See below. i get individual values instead of a totaled value.
Might be something wrong I'm doing on my end.

Can you share a screenshot of the settings of that custom property?
Sure, here's the screenshot:

We currently only have number aggregation for our built in columns like qty, measurement 1-3, and the cost/price/markup, etc. We do plan on adding aggregation to custom properties.
