Temporarilty hide all channels but L and R

Hi guys. I work a lot with synchronizing dubbed film audio tracks from TV/Streaming versions to Blu-ray, but in order to do so, I need to stretch both tracks vertically a lot in order to see peaks clearly. It's not possible to see them clearly while working with 5.1 tracks, so what I have to do is to first convert them to stereo, then do the sync job, and then do the masochistic thing of editing the .sesx file in order to replace source files with the original 5.1 tracks and trick Audition into thinking it was a 5.1 project in the first place.

I really want to avoid doing this masochistic job every time, but I just can't see peaks well enough if the tracks are 5.1 because they take a lot of vertical space, and my monitor isn't that big vertically.

How can I hide all channels but the first two (L and R) temporarily while working on 5.1 tracks?
