I have a webform but it's very long and users are going to use it a lot of times so they requested to have sort of like a cookie storage that remembers submitted data on some fields. For example I have a country field `country: text_field` (user inputs something).

I want to collect that country input from that user so when the next time user visits this form it will already have that country input in place so the users dont need to re-type it. I thought about having a cookie to store this but it feel likes it should be done in a different way.

Suggestions?
