Rewire, Reason and Automation ?

I use Reason as RackExtension Host and Sonar Platinum as DAW.
From Sonar i use Rewire to connect to Reason.
 
Within Reason i've an instance of ABL2 which i want to automate from Sonar.
I've also other Synth like Viking and RP Predator.
Is there an easy way of Mapping the controls of the different Reason Synth to an automation lane in Sonar?
In StudioOne3 one can simply select the controler of a rewire instrument to automate, in Sonar the list of controller is not given.
Any advice?
