Have you tried the mixer panel?
You can get to it under the PPro 2 Window tab – Workspace -Audio Editing setting, which will call up a mixer panel. You can leave everything in default (which would be read enabled over each channel fader) There is a scroll option for each fader. Select write for the track you want to modify. If your computer is capable of keeping up, you can mix in realtime including pans as if you were at a virtual mixer. Works great. It can be destructive when write enabled, So use some previews and sluff stuff to get used to it. Also under edit preferences you may need to set up the timeline to smooth scroll. I am not in front of my editor,so I forget the exact dialog to get you there, but it allows you to visibly watch the timeline continuously during your mix, and you can anticipate your mix accordingly.
