Include an option to set global limits, perhaps under "Default Availability", so that we can limit the total number of bookings in a day, week, month, etc. This way booking types can have their own limits or be tied in to a global limit. For example, I am a coach with several types of bookings (right now including for duration of bookings since there is no option for variable lengths in the same booking type), and I would like to limit the overall number of bookings I get in a day or week. At the moment, I cannot set a limit, as someone can book under a different booking type and I end up with too many bookings total. Thank you!
