How Do You Manage Appointment Types?

Hi everyone, I am wondering what appt types other Myotherapy clinics use?
We use Initial and Review, however the Initial appt type includes both new clients to the clinic as well as a return client who is new to the clinician.
The current setup makes it difficult to embed Patient Forms in appointment confirmation emails for new to clinic clients but exclude them from new to clinician clients.
I’d be interested to hear how other clinics configure their appointment types?
Thanks! Kara
