Approval routing for bank account changes excl new bank account creations or assignment end dates

Summary:

We have Procurement BU level bank account change approval setup, and it is first responder wins. The client want a specific separate approval rule when a user updates an existing bank account (i.e. changes the Account Number) to ensure other areas who 'share' that account are also forced to proactively approve. This should be include needing to approve scenarios where other procurement BUs are changing their interaction with that supplier bank account.

In cases where a individual procurement BU set up a new bank account for their supplier, this approval group should not be triggered. Similarly, if an individual procurement BU end dates their assignment to the bank account - this should not be routed to this approval group.
