If this uses the dynamic update protocol specified by RFC 2136 (Windows Server documentation says that this is the case) it should be possible to create a virtual server to capture the DNS traffic specifically and an iRule to modify the DNS UPDATE requests in-flight.

 

The system does not have built-in functionality for this.
