Drum Track Solution

Hi All

I am using Cubase 7 in which I have a drum track which has been split into several parts. I’ve been trying to find a way to increase the tempo of particular part for .e song chorus drum pattern and then when the song hits the chorus the next drum pattern is at normal speed. i have tried selecting the chorus drum pattern and using the track delay in the inspector to increase the tempo however this increases the tempo for the whole drum track and not the selected part. Finding a way to do this has been rather frustrating!!!

Any help on this would be very much appreciated.

Many thanks
