I think what you want can be done with some creative IR translation. Hijack sees the knob rotations as IR codes: 




#define IR_KNOB_RIGHT			0x0000000a

#define IR_KNOB_LEFT			0x0000000b


So I'm thinking that if you added the following to your IRTrans section, it might turn it into a jog dial, of sorts: 




a=20DF11

b=20DF10



No promises though. Give it a shot.
