I'm working in adobe audition and I have a very intricately designed panning patter for one of my tracks. I could go brute force and do it on each track (about 3, so not too tragic, probably an hour of work), but it'd be really nice if I could somehow copy/save the keyframes/levels on one track... I don't think that it's possible, but you never know!
I haven't used Adobe Audition before, but I suppose, that you used automation. You should be able to copy automation from one track to another.
Second option could be duplicate the track (with automation) and replace audio.
