Comping in S6PE?

I am really new to sonar.... Does anyone know if there is a feature that allows you to comp multitrack drum parts and such?

Can you give me a hint on where to start learning about it?

Here is the problem im having. Drums are done on 8 tracks. I open up track layers on those tracks, when I say use the mute tool on the first track take 1 it is not refelected on the other take 1's for the rest of the tracks....
