You should be able to customize any Quick Label. It doesn't make sense that if a patient has more than 1 appointment scheduled, it will only print out the next scheduled appt with your custom design. If you select the appointment so you can print the correct appointment, then you can't add your office info or anything to the card. We purchased the dymo label printer to print out the appt reminder cards thinking it would make things easier, but now it's just annoying because we can't customize all of them. Unfortunate.
