It would be beneficial if the price of an upgrade on the authorization page had the option to be linked to which quote the customer chose. That way, the estimate creator can have one upgrade option that works for multiple estimate options.

We bring this up after doing a roofing job where the customer had a side house, and every roofing material quote for the main roof also had an upgrade option for the side house. We chose to not use the upgrade option because it would have confused the customer if they had 3 of the same upgrade, but differently priced. Instead, we created 3 entirely separate quotes for the different materials along with their respective upgrade for the side house.
