Envelope adjusting for Multi Tracks?

Hi Guys, I have a question. Is it possible to make a single volume envelope that would adjust multiple tracks? For example, drums. Let's say I have 7 drum tracks and i want to make the entire 'already perfectly mixed in relation to each other' drums louder in a few spots... softer in others.... so how would i make an envelope under the entire Drum Bus that would alter all the tracks simulateously? Thanx in advance again for the imput, Maceman

Put all 7 drum tracks in a folder (so 9 tracks in total) Put a Volume Envleope on the Folder track.

Ahhh. Thanx for that. Makes sense! Cheers, Maceman
