How can I edit anwsers previously completed?

I need a form that can be anwsered, but that single anwser have to be edited by multiple people, at different times. Can JotForm do that?

Submissions can be edited from the submission view of your account at any time:

It is also possible to include and edit submission link in email notifications and autoresponders:

This will allow for updating specific submissions via the emailed link, rather than having to go through your account.
