Is there a way to limit the PPR (payment process request) to certain user?

Is there a way to limit the PPR (payment process request) to certain user?

For exmaple, if I'm a user of the BU A and create a PPR to pay invoices of that BU, how do I limit the visibility of the PPR to user of a BU B.

Not limited to BU criteria but any criteria, for example Pay Group, LE, Payment Method, Country, etc.
