Is the user able to delete their submission or choose another date?

Is the user able to delete their submission or choose another date? We use this form to have people sign up for workshops. Sometimes they need to cancel and sometimes they just want to change to another workshop date. Anyway we can make that happen for the user? Right now we have to make all those changes for them.

thanks!

With the submission edit link the user will be able to update their selections and data in the form.

However, they will not be able to entirely delete their submission record. The submission can be deleted only by you.
