Traktor S2 Sample Deck ?

Traktor S2 Sample Deck ?

I just bought an S2 and was trying to control a sample deck. On the mixer of the S2 can I use the fader on deck A to control the volume on sample deck C. Am I stuck using the mouse to control the volume on the headphone icon in the sample deck? Do I need to upgrade to the Traktor 4? Thanks

I don’t know if you can map the line faders for sample decks, it could be
.
but you’ve got a rotatory knob in the middle of the mixer that control the volume of the sample decks.
