I have my calendly set up for  different type of events.  Three of them are 1 hour in length and 1 is 30 minutes.  When I set the duration of the meeting for 30 minutes or 1 hour, that also sets the time the prospect booking the appointment can choose to an even 30 minutes or 1 hour schedule.  I would like to offer a client the ability to choose a 7:30 time for 1 hour, but cannot find a way to do that except for setting the duration for all the event types to 15 minutes and putting the time expected in the title of the event.  This causes some confusion though when the client gets the auto reply confirmation saying they have a 15 minute time on xxx day at xxxx am/pm.

Is there a way to set the available time selection to 15 minute increments for the client but have it reserve 30 minutes or 1 hour on my calendar?
