can I divide directory to subdirectories

[vietanh1977]

Hello

I wonder if I can divide directory ,which is wrote in option of named.conf file, to subdirectories to store difference my zone file.

for example:

In my named.conf I have option
directory "/var/named/"

I want to divide this directory to subdirectories as:

internal 
external
In two subdirectories, I will make zone files for my external network and my internal network.
