How can I fill out someone else's jotform in my account so that I can save and come back to it?

I have tried to complete someone else's jotform that was linked to me on Facebook. The problem is that it is a rather lengthy informational form and every time I get halfway or it's partially completed I'll have to answer a call or if I push the back button twice it submits it prematurely. It's frustrating not being able to save and return to the incomplete form. Is there a way I can save and return to a jotform that was sent to me to complete? It's really frustrating having to go back and reenter the information. Please help

We do have the feature to Save Forms and Continue Later but it may be disabled on that form.

Do you know who the owner of the form is? You can contact him/her and suggest to enable this feature on the form.
