Not yet ! It's been discussed quite a lot if you check the list archives.

Version 3.0.x doesn't - unless you want to hack the source.

version 3.1 has I believe the ability to set the identifier selection 
code. The default is match first value ( client-id, hardware) the 
same as version 3.0.x, but you could change this to match first value 
( agent.circuit-id, client-id, hardware) in version 3.1 to achieve 
what you want.

Version 3.1 is currently in alpha.
