To quickly add your customers to multiple classes, navigate to the book classes icon on the customer's profile, then select the membership you want to use, and which class type the customer wants to attend.
Click next and you will be taken to a page where you will be able to select the dates and times the customer wants to attend. Note once any limits on their membership have been reached no further bookings will be permitted.
Your customers will only receive one email confirmation for all the classes they have been booked into. You can customize the content of this email in Notifications >> Customise. The notification is called "Event: Multiple Sessions Booked".
