is it possible to add a listen directive during kamailio runtime ?

The reason I'm asking this is in a situation when I add a new peering trunk (from a different network segment), I need to add a network interface to the kamailio server and then add a specific listen directive for that interface to reference the socket by name.

listen=udp:10.1.1.11 name "mySN1"

so i can further reference to a specific socket name when routing SIP messages.

Please advise,

Regards,

Tihomir.
