Hi Mr Wal
Thanks for the post. Yes, our system does allow for you to send out automatic recall reminders although you will need to create the recalls first.
The recall reminder will allow you to specify the appointment type. So you could setup the recall rule to only send out a reminder to people who are due for one of your diabetic treatment types. So in short the answer is yes to your second question! 🙂
Please let us know if you require further information.
