Reply to Play cue when pressed

Alright, forgive my lack of proper terminology. I'm using Traktor Pro with the Numark Mixtrack. Is there any way with the controller or software (ideally both) that you can set a cue point in a particular part of a song that would serve as a sample? For example:

Say in a song there was a vocal sample that said oh, idk, something like "Drop the beat". Is there a way you can set a cue point at the beginning of that sample, and then only have that deck play while you hold down a button?
