Invoice Approval - Can we restrict delegations/reassignments to buyers?

Summary:

We have participants which are rule based by resource.
We have some cases where the approvers are delegating/reassigning the case to people from the procurement areas (usually buyers).

Is there any way to restrict their users so the cases can't be delegated to that group?

• The prohibit self approval wouldn't be an option from what the documentation says.
