I am selling one subscription for half hour and hour-long appointments. I want clients to be able to book both appointment types when purchasing this subscription and to see both appointment types on the same calendar. Is this possible or do they have to book the 30-minute appointments then another calendar to book the hour-long appointment? This is not ideal as they can't look at the whole week/month to see all the avaialility in one place. They are booking according to their scheudle rather than appointment typs in my case.
