Would it be possible where an existing appointment is booked, that the options given are those next to or nearest to the appointment already booked. This would mean our calendars could be better streamlined, i.e. appointments close together. I rent space and its fine if I have six appointments booked to pay for a full day but if Ive only two, and one is at 10am and other is at 7pm I still have to pay for the day but am tied to the location or waste the day.
E.g. Booking already in at 7pm, other availability is before or after only.
