Active Directory site aware DNS

I have a question regarding AD integrated DNS.
We currently run a 2003 AD with multiple sites, each site would have multiple subnets within the site.

Adding multiple DNS entries for the same A host record will cause DNS to perform round robin, this responds with a local site entry if the request is coming from the same subnet put if the request is coming from a different subnet within the same site it will perform round robin responses.

Is this the best AD integrated DNS can do? I see AD doing some nifty DNS responses for its NS entries and wonder if I can do something similar

E.G.

Site1, Site2, Site3, Site4, Site5, Site6 - all with multiple subnets

Two entries for media.domain.com in subnets in Site1 and Site6
I would like Sites1,2and3 to resolve to one of the entries and the other sites to the other entries.

Any assistance gratefully appreciated.
