Sorry, I misunderstood the original post. :-(

If you put all your zones which should be transferred into a separate file and 
include this into /etc/named.conf using "include /etc/named.conf.include" you 
could create a bash script which uses sed:

1. Modify all entries from "master" to "slave":
  
   sed s/master/slave /etc/named.conf.include > /etc/named.conf.include.tmp

2. Modify the end of each zone definition by inserting the address of your 
   master server (I guess there's a much more elegant way, but at least this  
   works):

   sed s/\}\;/masters\{1.2.3.4\;\}\;\}\;/ /etc/named.conf.include.tmp > 
   /etc/named.conf.include

   This replaces the "};" at the end of your zone definitions with 
   "masters{1.2.3.4;};};". So the formatting gets lost, but I guess that is 
   tolerable.

I hope I didn't insert any typos ... ;-)

Regards,

Peter
