sharepoint designer – Recover data from 2013 WorkFlow Start Task Process Task

First, I can not use the SPD 2010 platform.

I have created a custom 2013 SPD workflow with conditional approvers. Currently, I have conditional instructions that build a variable "email list" with different users, which is then used as the argument of the action "Approval of Startup Task".

I must be able to retrieve the comments of these users if they refuse. I realize that there is no task ID like with the action 'Assign a task', but is there any work around to get feedback from these approvers? Or maybe divide them into nested individual tasks in a parallel block?

Any help / help will be greatly appreciated!
