Take a look in the book DNS and BIND, 4th edition, page 476 which says
Requires the answer to be authorative, not from a name

this feature would have to be implemented in the name
server, and it's not.
So I guess you're out of luck with that at least unless and until the
BIND developers decide it's important enough to implement it.
