Can you add samples to a user expansion pack?

I created a expansion pack with a bunch of samples a while back but now I want to add a single kit with 16 samples into it, is this possible and if so how?

I figured out how to do it, I simply right clicked the program that I want and select save then direct the path to the correct folder in C:/Program data/Akai/MPC/Expansion (I think that's it, I'm going off memory) .
