yes, "don't" :)
You could write a simple script to modify dhcpd.conf as needed, but I set
up a lot of systems similar to yours for small offices. For a number of
years, I tried to use the ISP's DNS resolver, but after a while, I realized
that virtually EVERY ONE of the systems ended up with me installing a local
resolver on the firewall because the ISP's went down at some point.
Very true :-)
long time back I did this on my firewalls

you could use bind that comes with the base also :-)
