Appointment Book Queue for multi-chair ortho practices

TSO is a multi-chair busy orthodontic practice.
TSO relies upon a streamlined way for multiple patients to be seen at the same time by 1 orthodontist only.
To be able to do that the chairs are operated by nurses, hygienists and oral therapists. The orthodontist floats from chair to chair on the sequence of that the patient has arrived or that the next step of the appointment is ready to be checked.
TSO is kindly request that a queue system is developed and made visually available on the calendar layout.
Please see the examples of the proposed QUEUE system on calendar attached to this request.
Regards,
Dr Will
