With the new bookings module, there is work being done on 34440 to add prep days on either end of the booking to allow the library to gather materials for sending. In some libraries bookings is its own system/department, and is not open every day of the week. It would be helpful to be able to define "booking days" similar to 'curbside hours' and to take these into account when bookings are being placed. i.e.: A booking is being placed to begin on a Monday, it requires 2 warm up days, the bookings dept is closed on weekends. The booking period will need to include the Thursday and Friday of the week before. Similarly, a booking ending on Friday would need cooldown days on Monday and Tuesday
