Add DNS without Plesk

[jerry2]

I really don't want to cheat on Plesk, but I have 10 licence version with my rented server. I use the server only for a backup purpose and I use it as a secondary DNS server. Problem is every DNS takes one domain...

Is there a way to just add DNS entries to BIND without interfering with Plesk? I made a entry in named.cnf and it got deleted when I restarted DNS server :-(
