R12: How to setup AME Timeout feature for workflow POAPPRV

I am trying to determine how to setup the Timeout  feature for PO AME in R12.

In reviewing Note:973699.1, the feature was rolled out in:

Patch 18336912: This Patch introduces the functionality to send Reminder Notifications on Timeout in Requisition AME Approval Process

Is anything available for PO AME?

I did attempt review the workflow file to see if a timeout feature was released

1) Using WF Builder, open the Approval workflow

2) Explode the Processes menu

3) Open subprocess named "Parallel Approval Subprocess"

I see there is a function 'Reminder Process' but not able to determine the process flow.

Any help would be appreciated.
