Is there any way or workaround to simulate “First Responder Wins” functionality?

  I would appreciate if someone can help me in the below issue.

 

Is there any way or workaround to simulate “First Responder Wins” functionality?

 

We are using AME. And we need to do the following:

 

We need to build the following approval list:

1- One static person A.

2- Group of people (static or dynamic) B.

3- One static person C.

 

After approving the Purchase Requisition  (PR) by A, we need to send the PR  to a group of people (B) and when any one of the group approve the PR, we need the PR go to approver C.

 

As the “First Responder Wins” is not supported on 11.5.10.2; we need to know if there is any workaround or a way to achieve our need.
