Create a new kit with sounds from different preset kits

So, I recently acquired a RYTM mkii in a trade - and was actually supposed to sell it. But it’s too damn cool, so I’m keeping it.

Going through all the preset kits, I found sounds I like on different kits.

But what would be the best way to go about merging all the sounds I like from different kits into one new kit?

RYTM has a Sound Pool like on the DT, right? If so, load the kit, save the sound you want to the sound pool, repeat.

Then load a blank kit, and load the sounds from the sound pool onto the tracks, save kit.
