Zones list mask or wildcard

[Dimitry Bansikov]

As I wrote earlier, I have 1000 different zones for domains. And to add 
a new zone or delete an old one, I have to change a file with a large 
list of lines "zone domain IN {...};".

I need to simplify adding and removing a domain so that it is enough to 
just add the zone file itself whitout editing the big list. Is this 
possible? There are simpler options?
