Online Booking Confirmation Emails to Contact Name

We have just turned on the Group Booking setting for our Online Enrolments and I've noticed the person who is the contact name gets sent the booking confirmation (sent from Default Templates) for each person in their booking. For example, if 6 people are booked in the same booking then the main contact will get sent 6 confirmation emails (all in their name).

Is there a way to turn this off as it's not the best user experience for someone to be getting multiple of the same email?

Thank you!
