Different drum rolls in cubase groove agent Se

I would like do programm “drum roll” repeats in groove agent se, e.g. 1/4T, 1/16 et cetera (for a live setup with different pads for the snare drum, to create different synced snare rolls with different keys). In other words: the things that are possible with the delay in groove agent se, but not as delay but as roll. Is there an elegant way do realize this?

Kind regards
