I am using O365. I have a SharePoint 2013 list document with  a Nintex form. Attached to this form is a Nintex workflow with "Start a Task Process" running in parallel. Each user (anywhere from 1-6) is assigned the same task of reviewing the information on the form and adding their comments on the form itself. (I currently have comments area as a repeating section.) How can I keep comments from Reviewer 1 from being overwritten by Reviewer 2, etc.

Thank you.
