Resending form for client to edit to add signature

is there a way to resend a form for client to add signature without editing the whole document?????

You can allow your users  to edit their submissions at a later date. Unfortunately, you are not able to allow for your users edit specific fields with {edit_link} function so there is no limitation for editing the fields with Jotform. If you have any question or issues, please do not hesitate contacting us. We will be glad to assist you.
