Allow any participant to edit text in form fields

I have an Adobe Sign template with text fields that I would like to allow any participant to edit.   This is how I would like it to work:

Participant 1 enters information into the text field and signs the document

Participant 2 can edit the information entered by Participant 1 if necessary and sign the document

Participant 3 can edit the information entered by Participant 2 if necessary and sign the document.

I have accomplished this with Adobe Pro but not in Adobe Sign with a workflow.

Also, I've uploaded the form that works in Adobe Pro to Adobe Sign as a template but haven't had success that way either.

Any help would be appreciated.

Thanks!
