sharepoint designer – Retrieve data from the WorkFlow 2013 start process task

First, I can not use the SPD 2010 platform.

I have built a custom SPD 2013 workflow that has conditional approvers. Currently, I have conditional statements that create a variable of & # 39; email list & # 39; with several users which is then used as an argument for the action & # 39; Start task approval & # 39;

I need to be able to retrieve comments from these users if they reject it. I realize that there is no task ID as with the "Assign a task" action, but is there a solution to get comments from these approvers? Or maybe divide them into individual tasks that are nested in a parallel block?

Any guidance / help with this will be greatly appreciated!
