How do I resend form for second signature?

Is there a way to resend an already filled out intake form to have the client sign it for a second time/date?

I have clients that come back to me for a second appointment and it would help if they could resign their initial paperwork instead of having to fill out completely for a second time. 

You can give them the submission edit link. To form an edit link, you need to get the submission ID of the submission: Where-to-Find-the-Submission-ID.

Then form a link like this: https://www.jotform.com/edit/{submission_id_here}
