Queue Management with Kannel ?

Hi all ..

  I am working on an SMS application . Which is due to send large no.
of message to multiple smsc ports.
  Some message among them will be having priority specified t them e.g.
urgent .
  as kannel manges the message traffic itself, is there any possibility
of managing the  message queue destined to the SMSC.?
  so that urgent messages can be sent as fast as possible .

Regards,
