When a family selects the wrong entering year for a student on an event registration form, there really needs to be a way for us to fix the entering year before processing the form. The duplicate work involved -- downloading the registration form, manually uploading it, making sure it did not delete the registration on the Event side when you delete the wrong entering year on the student's record -- is so cumbersome and easily solved by making those fields editable on the processing side.
Absolutely! And it should really check to see which data we want to keep, just like when we process an Inquiry or Application.
