Book more than one session before check out#1503

I run mulitple group fitness sessions and at present you can only book and pay for one at a time. I need them to be able to book multiple classes and then checkout and pay for the total in one go.

E.G. If someone books a class at 9am, and then also wants to book the following class at 10am, and pay in one go, they currently cannot do this.

Extras isnt an option, as i need each session to have a maximum number of customers attending. And using the example above, if they use Extras, it wont come off the number of attendees at the 10am class, so I could get over subscribed for a session and not everyone can attend.

It seems odd that you can only purchase one thing at a time. Surely other people who book classes may want to book more than one class at any time and only have to pay once?

There is a further issue for me, as people get a discount (coupon) to use if they book more than one class, so I hope that your tech team are able to add this as a very useful function asap.
