The Appointment Time Pattern should not block an appt from being booked if there are too many Xs or slashes. Our practice does not use them and it's time consuming to have to go to that area to alter the time pattern just to be able to book an additional appointment. It should allow us to book as many appointments as we choose without having to alter the time pattern.
It is very time consuming when we cannot schedule an appointment without adjusting the time pattern. We do not need time patterns at our office.
