Re-assigning PADS in Rekordbox

I'm looking to re-assign my Beat Loop pads in Rekordbox when utilizing my XDJ-XZ. 

Currently, Pads 1 - 8 are assigned as follows: 1/4, 1/2, 1, 2, 4, 8, 16, and 32, respectively.

I use the 128 Beat Loop religiously, and I'm trying to re-map that value to Pad 8. 

Ideally, I would like to get rid of 1/4 and 1/2 on Pads 1 and 2, and add 64 and 128 to Pads 7 and 8.

I opened the MIDI function in Rekordbox and was completely lost. 

Any help/advice would be greatly appreciated.
