ALterntive for channel switches (instant quick cut channel cut out)

I have a Prime 4 and Prime Go is there a way to kill the sound instantly?

I user to use the Pioneer DJM600 with turntables and we would use the channel flick switches to do minor instant cut outs during mixes, rather than doing it on the cross fader.

Are there any buttons on the Prime that would kiss the sound in the same way - a quick ON/OFF ?

Crossfader or linefader with sharp curve, touching the platter with slip mode on, 100% wet delay set to 4beats,…lots of ways.

But why the F not just use crossfader, it is designed for that purpose???
