Match Airbnb's most popular option by adding a "days after booking" tab to the cancellation policy menu

I would like for all my API channels to follow Airbnb's most popular cancellation policy so everything is consistent. The popular Airbnb cancellation policy is 100% refund within 48 hours after booking and then a 50% refund up to 30 days out. Your current configuration hinders this approach across all channels because the cancellation policy is always tied to the arrival date.  Can you please add a "days after booking" tab to the cancellation policy menu (tab in question circled below)?
