Toraiz SP 16 Rex file support

I have so many rex files.  This would speed up workflow instead of chopping up the samples all over again. I have years worth of breakbeat samples chopped up as rex files, thousands of files; please don't make me do this all over again.

Akai, Ableton and Maschine have these features.

I have an mpc live on order but I really want Pioneer to step up and add some very basic features that should have been included from the beginning.  

I'm hanging by a thread guys.  C'mon
