Digest volume numbers

["Bob Bish" <bish @ azstarnet . com>]

   I've been increasing the digest volume number by one after 100 digests.  For 
example, it recently went from Vol. 10 Number 100 to Vol. 11 Number 1.  I've 
been doing this manually by changing the numbers in the digest config file each 
time.
   Is there a way to configure it to do this automatically?
