Reply to itunes Imports Into Ableton Using Push Controller

Hey there everyone, I'm a bit new here, and i have a rather stupid question since i'm not too familiar yet with ableton and the push controller.

What I am looking to do is to use the Push controller to browse my itunes folder that i have set up in ableton on the side bar. so far i cant find any way of doing with with out remapping the controller.... is there an easy function i just havent found yet? the browse button only lets me browse ableton items and sounds it seems. Any help ould be appreciated! Thanks.
