Implementing Client Subnet DNS Requests

Hi,
is there a way to tamper with the DNS response based on this information? We are running GTM. When the listener is receiving a DNS query, I would like to decide which virtual server out of the selected pool is used and posted back in the dns response depending on both location (based on the EDNS information) AND availability of the respective resource.
So, ideally, in analogy to the GSLB "Topology Record Builder" settings, I would like to set the datacenter information, but not based on the Client-IP in the Layer3 Header, but based on the EDNS client information, as shown in the code snippet.
Is this possible? Thanks!
Regards, Matt
