I would need a function that allows me to list the door codes together with the other booking information. This could be achieved either by allowing the user to configure the columns shown in the bookings table view or allow the printing/export of a list, that can be configured using the placeholders available in the email functions.
If for some weird privacy or security reason, this wouldn't be permitted, I would be happy with a list of blocks/bookings that don't have a Door Code yet (field is empty).
