Time slot creation/control and recurring appts.

I want to have 60 minute appointment time blocks, but some start at the half hour, ie 6:30. If I make a small increment of time block ie 15 minutes it appears I can not control when the appt starts. The client could pick a start time at any avail 15 min increment, whereas I want say 7:30 or 8:30, 9:30 starts only for 60 min appt. How can I set this up.
2. Is it possible for a client to request and get recurring appts. i do coaching and often it is an every other week, same time for 3 months. can this be done (I am not a programmer :slight_smile:
Thanks!! Looking forward to hearing back
