How to make increased pitch sound group

Hey there I'm trying to make a sound group that increases pitch. I have it set to top to bottom variation sequence and 10 voices. What I want it to do is start at the first variation (lowest pitch) and if the sound group is triggered again, increase the pitch. However, if the sound dies out or after some amount of time I want it to restart at the lowest pitch again. Right now, it seems to continue at the next pitch even after a long delay. Is there a way to do this? Just wondering, thanks.
