Loading a Sample to a Specific Pad

i just switched from the 1k over to the 2500. On the 1k with my JJ os i was able to...

go to the load screen ,find a sample, press load sample, and then it would ask me what pad i wanted to load it to i could then press the pad i wanted the sample to go.

I cant figure out how to do this on the 2500 with the jj os. Is it still a feature on this OS? It was really helpful when i was making drum kits.

you have to turn the sample to assign window on.
mode + pad 2(load) Go to the sample you want to load, press window then it gives you the option to turn the assign to pad window on.
