During Internal Supplier Profile Change Request - Can we put Supplier as one of the Approver.

When any changes has been made to Supplier Profile by the Internal Team, Business wants to put Supplier as one of the Approver.

By this Supplier can also validate and give the confirmation that all changes made are ok.

I found a work around that we can put Supplier as Approver using a Route Task action available to the approvers but that is manual task, is there any other way where we can directly put Supplier as one of the approver.
