How cut a slice in an Audio Montage?

Hi to everyone. and, please, sorry my Eng. I’m from Italy.
Using Wavelab 9.1 on Windows 7.
I have an audio montage with 20 tracks and I would need to “cut” a couple of seconds to track 8.
How can I get all the editing to be “slipped back” by those two seconds without having to relocate each individual file from scratch?
I hope I’ve explained well what I need.
Thanks in advance to anyone who wants to explain to me how to do it.

EDIT : Excuse me, I forgot to to specify that I’m using an audio montage consisting of two stereo tracks. :slight_smile:

Found it!!! :slight_smile: Thx the same … it was really simple … :slight_smile:
