Unnecessarily complicated command formats for add-prescription, edit-prescription and delete-prescription commands

[jibtaf]

The format for the commands are: add-prescription APPOINTMENT_INDEX pi/PATIENT_INDEX mn/MEDICATION_NAME..., edit-prescription APPOINTMENT_INDEX pi/PATIENT_INDEX mn/MEDICATION_NAME... and delete-prescription APPOINTMENT_INDEX pi/PATIENT_INDEX. In my opinion, the pi/patient-index does not seem to be necessary since the users should perform this command after doing list-appointments patient-index, then it does not add more value to probably add/edit/delete another patient's prescriptions here.
