Send the information submitted notification to all the approvers instead of the requester

Customer requirement:
Create supplier change request which requires approval from an approval group with 6 members.
Supplier submits profile change request and notification is sent to all 6.
Now one of the members says request for info and supplier receives the notification.
Supplier submits the notification and requester received the notification.
But now customer says when information is submitted all 6 users should receive the notification.
We are using parallel approval first responder wins.
