I doubt there is anything like that

Imho, if you can set up zone on master server, it should be not much work to
do the same on slave. If that happens often, you may set up scripts that
will create files and distribute them to more servers.
Also, you can look for alternative servers like MyDNS, that run over
MySQL/postgres database and try to configure replication of databases, which
will kinda do what you want, but different way.
