The left preview Button on my S4 MK3 has become buggy. I hold it and use the rotary knob to preview the track. Is there way to use the the rotary knob as it was on the s4 MK1? Holding it and scrolling to preview a track? Or how can I map one of the below buttons (Fav and Library Switch) to be the Preview button? But Iwould favor the 1st Option. THX
