One trick would be to define several "virtual" clients. On a Unix client
you could have several stanzas in your dsm.sys:

SERVERNAME A
   NODENAME                 CLIENTA
   TCPPORT                  ...
   TCPSERVERADDRESS         ...
   ...

SERVERNAME B
   NODENAME                 CLIENTB
   TCPPORT                  ...
   TCPSERVERADDRESS         ...
   ...

You can bind CLIENTA and CLIENTB to different policy domains with different
default management classes. To perform a backup as CLIENTB, you use the
-servername option:
dsmc incr -servername=b
dsmc incr -servername=b
