Adding key shift to XDJ RX3

Hey, as a DJ i love using harmonic mixing, almost all of the time. I own a RX3 which is awesome, but unfortוntally there is no option to change the key (key shift) while using it in a stand alone mode (which is basically the whole purpose of this device). As a result, i have to use the RX3 as a huge controller, and always bring my computer with me.

It will be perfect if you could add this option of key shift also to stand-alone mode (like this option exists in cdj 3000), so DJs could actually enjoy this amazing device like you meant to!

Thanks.
