This seriosuly needs to be added to the top of the priority list for HubSpot. Having to double the monthly cost of our subscription to add a field that will perform a simple calculation so our integration with PandaDoc will work the way we need is unexceptable. I just got done chatting with a support specialist who recommended I use webhooks to accomplish what I need to do and after doing some research webhooks are also not an option without the enterprise subscription. Please give the pro version a stepping stone to enterprise and add calculated fields a paid addition just like the advanced reporting feature.
