Network Security Policy -> Blocked Zones

I was wondering where are the hosts in the Blocked Zones being stored? I have certain hosts I have to block/allow constantly so instead of opening the dialog I wondered if I could just create a batch file to modify some text file.

I myself couldn’t find such file, but maybe there is one.

If there isn’t it would be very thoughtful of you to make these hosts as a text/xml file that could be modified from outside.

Thank you!
