Reply to S4 output routing

Hello everybody,
I am french, so sorry for my very bad english ! I hope you'll understand my questions....

I have the NI S4, and I use it with two turntables, with the timecode technology.

I work with a musician (a drummer) and he prepare a "tick" in audio.

We would like to do this configuration :
Deck A and Deck B : Main out (with the turntables)
Deck C : The tick. The drummer only can listen it, in its headphone.

Can I make a routing with the deck and the output of the S4 ?
L Output : Main out (Deck A & B)
R Output : The tick (deck C)

Many thanks in advance for your help !!!
