Can dhcpd update DNS CNAME records?

Our schools are successfully having the dhcp server update the bind DNS 
entries A and PTR records.  I would like to include CNAME record updates from 
the dhcpd.conf file, how would I do this?

  host a100-10 {
    # Note: principal's laptop
    hardware ethernet 00:17:31:63:34:58;
    option cname "principal";

I need the regular A and PTR entries to follow one naming convention for host 
names, at the same time It would be very nice to have a CNAME alias to access 
the cryptic host name.

Is there a way to have dhcp server update CNAME records?
