How to let users update their form submissions

Is it possible to send my clients a form that has their previous answers already filled in?  I would like to send them a form that shows how they already answered the question and then give them the ability to make a change to that answer.  For example, if they have changed employment, I would like them to be able to change this on their form.

It is possible to let users to update an entry inside of your form on a later date. To do that, first create an auto-responder email. Then add {edit_link} tag to the body of the email.
