NSD conf/zone templates

I set up a VPS to run NSD recently, and need to replicate zones via xfer to a secondary nameserver (not running cPanel or DNS-ONLY). Looking through the NSD documentation, it appears that I cannot specifiy a server-wide slave to use for all zones. Rather it's set per-zone entry in /etc/nsd.conf.

When adding a zone (account, addon domain, etc) cPanel configures this:

Code:

zone:
        name: "host.example.com"
        zonefile: "host.example.com.db"

And I need it to automatically configure:

Code:

zone:
        name: "host.example.com"
        zonefile: "host.example.com.db"
        notify: 1.2.3.4 NOKEY
        provide-xfr: 1.2.3.4 NOKEY

Since all zones would be configured for the same secondary, the easiest thing would be to find the template that the cPanel uses to create the nsd.conf file.

I can't seem to find the template that cPanel generates this from.
Any suggestions?
