The ability to directly open a premiere project in Audition to do the audio work is great, nice job Adobe. But, I often use 'fill left with right' or right with left as the mic is normally only into one channel or the other channel is unsuitable. It is a fast 'effect' added at track level in Premiere but it is shown as not supported when you open the project in Audition. Messes up the entire audio at the point where you want to finish the audio. This would be so helpful for video editors, please
