Edit data on stateless connected forms

Edit data on stateless connected forms

Hi,
I have five forms connected using Stateless Master form. I am able to submit the data on all the forms and submit it. 

Now, how can i make the data submitted on Form 1 be editable if i navigate to Form 1 from Form 2 using the "Next" "Previous" functionality.

Is there a way i can autopopulate the Form 1 using some ID?
Also note that I have not yet completely submitted the entire application (from Form 5).

Thank you.
