Customize the Booking Overview screen with custom fields

I would love the ability to customize the Booking Overview screen (first screen visible when clicking into a booking from the calendar) with helpful information from the Custom Fields that we have incorporated into the booking process. For instance, guests type in the reason for their visit via a Custom Field. Being able to select that specific field to be visible on the Booking Overview screen would make it muuuuch easier and streamlined for various processes on our end.
