Appointment type to match text message

It would be great if somehow the appointment type can correlate to a specific text message so it doesn't need to be adjusted manually.

For example - we have different appointment types that require different text messages.
1. Initial appointment - please arrive 5 minutes earlier to complete paperwork
2. Pilates text - confirming the group class, requires a Y reply
3. Case conference - we often book the patient in for a case conference (for billing purposes) but it's important they don't receive a text message as the appointment is with the clients GP or case manager
4. Pre-employment assessment - Client is required to bring specific paperwork, arrive early etc...
5. Hydrotherapy class - located at offsite pool so address required

Thank you
