v1.7 Individual Email for Each Ticket?

We've noticed in version 1.7 of jTicketing that now when a ticket buyer purchases tickets they receive individual emails for each ticket, as compared to receiving one email with all tickets in v1.6. Why is this the case? When a user buys 5 tickets to an event and receives 6 emails (one for each ticket and the order's receipt), not only is it confusing to the buyer but there's a much higher likelihood that the emails will be labelled as spam.
