Specific need: to apply a discount to food & beverage Subtotal, while other items are added to the estimate without adding to the discounted Subtotal. So, the Subtotal line may fall in the middle of the estimate, if that makes sense. This works only when in Windows. I often use the app on iPad using iOS. A Subtotal line added in windows shows when I open in the app, but doesn’t update with changes. Additionally, I can’t find a way to add the Subtotal line when creating the estimate in iOS app.
