How can I restrict access to only approving supplier bank accounts

How can I give access to approve supplier bank account requests but not give access to update anything else related to suppliers? When I add the function  "Supplier Full Access : Buyer View" to the responsibility's menu exclusions, it prevents update access to supplier menus on the left pane of the supplier page.  But it also prevents me from approving supplier bank account requests.  I have attached a document showing the only thing that I am trying to give update access to.  Everything else in the supplier pages should be view only access.
