How to manage protected DNS?

[aseques]

Good morning,

I've seen that in the database from ispcp 1.0.7 there's a field stating if the dns zone is protected or not.
A protected dns zone is the dns createt by the system administratro that the domain user cannot change.
I can add those entries via my custom CLI (http://isp-control.net/forum/thread-4255.html), but I'd like to know if that can be done via the web interface, and how can that be done.
Also, is that available on trunk?

Thanks
