Pre-Listen

Is there any possible way that I can map the pre-listen function to a button on my DDJ-RZ?

I would like to use the pre-listen function because it's extremely handy (as a wedding DJ) when people sometimes request songs I don't necessary know. Currently I have to load the track into a deck and do it that way.

I never use the actual pre-listen function, because the waveform takes up too much screen real estate and it's just another thing to "click" on my computer, when I'd rather be using the DDJ-RZ buttons.

Thanks :)
