How can I map the jogwheel for 2 funtions?

Hey all, I dont really know much about modifiers and am somewhat confused by them. Anyways all I want to do is take my mixtrack and have the outer of the jogwheel for pitch bend or whatever it is, and scratch on top. Basicly I want to not have to toggle the scratch on/off button. I am using traktor scratch pro 2.5, If someone can tell me how to do this, it would be much appreciated....
