Currently there is no way to definitively tell if the person included in the registration/webform submission is linked with a particular payment for the event. For example: a parent (with a different name) signs their kid up and pays for a class. The parent's info will be on the order, and the kid's info will be on the webform submission. The webform submission will be marked as 'paid', but there is no way to know 100% where the payment came from. It would be a great help, for accounting and record keeping purposes, to add the transaction id number from the payment gateway to the webform results.

This is an excellent module otherwise.
