NEED HELP ON FACTORY MULTISAMPLES COPYING/LOADING/USAGE

[2015korgpa3x]

Hello All,

I just start learning how to edit sounds and really had difficulty to do below.

I really want to know how to copy below factory multisamples to USB (or built-in Hard Drive on Korg PA3X), load onto Korg Pa3X, use and have them displayed as "User PCM Samples" box in the SOUND MENU (in Sound Editing mode) and available for selection while doing sound editing. (Please see youtube video (https://www.youtube.com/watch?v=f7N4fkCBUeI at the 1:13 minute) for reference to "User PCM Samples" box displayed in the SOUND MENU:

Piano Resonance OT L
Piano Resonance OT R

Tenor Sax Riff Up and Down
Alto Sax Vibrato 1 and 2

EL Guitar Short Noise
EL Guitar Fret Noise and many others

Your suggestions, advice, and instructions are gratefully appreciated.
