berlymahn - I personally use an alternate technique altogether. Just suggesting it for consideration.
Whenever I freeze a track I freeze it without effects or ProChannel stuff. The exception is guitar tracks going through an amp sim like Guitar Rig, where I'm freezing the track in order to capture the amp sim sound and take the amp sim out of the CPU.
Then I also create an empty audio track. I select the frozen track and copy, then paste the audio that is grabbed from the frozen track into the plain audio track.
I then can apply effects, the ProChannel, automation etc. to the audio track as desired. I mute the source/frozen track and use the audio track copy for playback and mixing.
I've found I gain advantages from this method and I do it for all tracks I freeze.
One advantage is flexibility. Previously if I had applied a bunch of edits to a frozen track and I wanted to go back for a quick fix on the source track, I would unfreeze and lose all the edits, which was disheartening. This way I can unfreeze and even change the source patch and not lose the edited audio track.
In reference to your question, this method also allows me to clearly keep separate and editable the ProChannel and other effects on the audio output.
