Space automatically reserved based on custom field answer reserving connected space

Our High School has seats that extend out into our cafeteria for the auditorium. When the auditorium is reserved and need the seats pulled out into the cafeteria, we would like to have MLSchedules automatically reserve the cafeteria if the custom field (Extended seating needed?) to request the seats in the Auditorium request, is responded with a yes. We have had instances that have been missed and a double booking occurs in the cafeteria. This would be helpful for those approving the multiple spaces.Thanks.
