Is USB browse (in remotebox) possible with XDJ-RX like it is in the XDJ-R1 ?

Hi,
i would like to know if it is possible to browse USB content of USB drives connected to the controller using remotebox on my ipad ?

From what i see on videos, it seems only possible to load and read from the ipad contents but not browse a usb device connected to the XDJ-RX with it .. is this right ?

I really liked browsing the USB files with my ipad (like on the XDJ-R1) - much faster search and selection.. would really like to see this on the RX.

thanks
