Logic Pro 9 Getting stereo inserts in MIDI FX side chain


EDIT: Please disregard. I found my answer here.
A big thanks to John "Skippy" Lehmkuhl for posting the video.
I wasn't clicking the stereo button for Bus 1 in the mixer.

-----My question was this:
When launching a MIDI-controlled effect such as "The Finger" the Sidechain pulldown only displays mono possibilities:

Audio 17
Audio 18
Audio 19
Audio 20

Input 1
Input 2
Input 28

Bus 1
Bus 2

So I'm getting the effect on half my stereo signal (I'm effecting an audio instrument).
How does one use the incredibly good MIDI-controlled effects in stereo?

I imagine I'd want to see this from the MIDI effect side chain pulldown:

Bus 1-2 (aux)
Bus 3-4 (aux)

Many thanks,
