Is there a way to customize the appointment emails?

I want to use the appointment feature in Keap but there doesn’t seem to be a way to edit or customize the content included in the appointment confirmations and a reminders. Is there a way to do this that I’m missing? AND are the reminder times editable? (I’d want more than 24 hours notice for a cancellation/reschedule plus indicate a fee in that email reminder)

Would be nice to have full scheduling capability so I could do away with my current scheduling tool.
