Changing keygroup gates on a z8?

Hey, im sure this is easy to find, but im out, internet free and seriously typing this on my phone. I have a keygroup program i just put into my z8, but the gate on all the samples (like 80 of them) is set to one shot. I know how to change the gate on the sample edit screen, but is there an easier, faster way to either change the gate on all the samples or to change the gate of the program? I know how on a 4k, but i cant seem to find it on my z8. Thanks

Ok, I still can't figure this out, so hopefully a little background can help.

I'm using samplit to get a few sounds out of my roland xv3080 into my z8 . I've got the sampling down, I then save as an sf2 and then use extreme sample converter to convert from sf2 to akp. All of the samples, in the sample edit screen, show NO LOOP, not one shot, but when i play the program in the multi screen, everything is one shot. The other thing that I can't seem to get to translate over to the z8 is that in extreme sample converter, I use the autoloop section on some of these, and there is definitely no looping going on in the z8. So yeah, any ideas?
