Jack,
DNS has an order of flow, depending on whether the inbound DNS request matches DNS irules, WideIPs or DNS express. You should be able to achieve what you desire by configuring the DNS Profile and assigning a pool of your internal DNS servers. This way any request not handled by DNS Express will be forwarded on.
See Overview of DNS query processing on BIG-IP systems and Overview of DNS Profile
These should help.
