Xone 4D BPM Display + Traktor

Hello DJ's,

I own an Allen & Heath Xone 4D and I use it with Traktor.
I love this mixer, it's really nice for live performance djing.

I've got one question about the BPM monitor on the mixer, it detects the beats quite good, but not perfect.
I would like to send the BPM to the Xone 4D from Traktor (depending on which deck a,b,c,d is playing).

Could anyone tell me how I can do this?

Thanks!
