There is no mechanism within BIND to do this. Believe me, if there were, I'd
be using it. This is not to say you couldn't write some utility that
periodically zone-transfers the external version of the zone, figures out what
has changed since the last time, and then automatically adds/deletes/changes
entries -- either by using Dynamic Update or just changing the zone files and
reloading -- in the internal version of the zone to make them match.

Or, you could just wait for BIND 9's "views"...
