HIFI H2 Pitch Shift (chipmunk effect) Available?

[GreatLove]

Hi there. I use ipod 6 classic and Rockbox has pitch shift that I love especially that it does not retain pitch it slows the music down/up chipmunk style, exactly how i want it. I just bought HIFI Walker H2 and was wondering if that option with rockbox is available on h2 also? And does it change it "chipmunk" style? If not, please i beg you to implement it as a request, i payed 150 $ for this mp3 but I won't keep it if this function is not available, I really want to keep it. Regards
