Modified functionalities

Hello, I’m really enjoying your theme and plugin, but I need some extra/modified functionalities to be applied in order to work for me 100%.

1) I need to assign Doctors to specific Patients in order for each Patient to be able to choose only among the assigned Doctors and not all the available Doctors.

2) I need the “Add Service” form fields to be present in the form of “Add new doctor”, in order to create a Doctor and a Service at the same time. Then a Patient should not be able to choose any Service in the “Add new appointment” form, since the service is already defined by the Clinic Admin – I would like the field to be displayed, but only showing the defined option.

Any ideas on how this can be achieved?

Thank you in advance,
Constantinos
