Does functionality exist to prevent specific values from being used in the Account Segment?

We would like to restrict specific Account Numbers from being used when creating a PO, creating an Expense Report and on the Payables side. We cannot use a Cross-Validation Rule because we do not want to restrict these accounts when creating a Journal Entry. We cannot create a Payables Account Rule because we want the transaction to stop, rather than update to a different Account Number.

Is there other functionality that we can leverage to restrict end users from selected undesired Account Numbers when creating a PO or Expense Report or when creating an invoice?

Thank you,

Rachel
