multiple slave zones pointing to same file?

[online-reg]

Hi All: I’m building a new Bind 9.7.1-P2 slave server and am taking an 
opportunity to review my conf files.

I have a number of zones on the primary that all point to the same zone 
configuration file. On my slave server, is there any way to configure 
named.conf so that multiple zones are all “aliased” to the same zone config?

Previously, I was using a basic slave config statement for each zone:

zone "domain.com" { type slave; file "domain.com.zone"; masters { 
192.168.0.1; }; };

but, it seems like a lot of unnecessary files are being created?

I thought about using the same file name for all the slave zones statements 
in named.conf, but wouldn't that force the file to be overwritten multiple 
times for no reason?

TIA
