Rescheduling appointment on the same day not allowed while using 1 appt per day scheduling limit

I have set a scheduling limit for 1 appointment per day. Unfortunately this limits clients also to reschedule an appointment on the same day. Apparently Squarespace Scheduling handles the existing appointment (which needs to be rescheduled) as the limit for that day. The clients thus needs to cancel the appointment first, or reschedule it to another day, before he can schedule it again on the previous day.

Is there anything to do about it?
