Reply to Start Cued Point on Crossfade

I am very new to DJing as well as the S2 Controller but I was wondering if It is possible that on CrossFade the track that is cued up will start playing without having to hit play. Maybe it already does this but it hasn't worked for me. If someone can let me know if this is possible or if I am asking for to much or how to map it that would be great.

Thanks
