Cisco IOS as DNS server

Dear Community!

Could someone help me to fine-tuning DNS server configuration?
I'm configuring an IOS router act as a DNS server with the following parameters:

ip name-server [IP #1] [IP #2]
ip dns server
ip domain round-robin
ip domain name []

The 1st DNS server is a public DNS server accessible from Internet, the 2nd one is a private corporate DNS server accessible from a site-2-site tunnel.
The client PCs at the remote end of the IPSec tunnel should query public DNS names from public DNS server, and the records of our private DNS domain.

Is it possible to configure a "policy" to query corporate DNS domain from a our corporate dedicated DNS server, and the other public DNS name from the public one?

Thanks in advance!

Best Regards,

from Budapest, Hungary
