XDJ RR Vinyl Speed Adjust

Hey, I used to be able to adjust my vinyl speed when using my DDJ-400. I really loved the effect of slowing down when you paused the track, it could lead to some great build up effects. 

I've realised that since having my XDJ RR you cannot do that! Seems crazy that this feature isn't included somewhere. This is super annoying as I can no longer do that effect when playing off my USBs.

This is a feature suggestion, I really think it ought to be included!
