How can I use all tracks from multi-channel source audio with Multicam clips?

Question

I cannot figure this out. Working in Premiere I'm prepping for a 2 camera show, with typically 4 to 6 track dual-system audio recorded by the sound guy. I can sync, and make multicam clips any number of ways–whether sync by timecode, sync by audio, or eyeballing–but whenever I edit using the MC clip, Premiere mixes down all the audio channels into a stereo single track, and I cannot pick and choose which audio track from the original to use. With 2-5 people mic'd on lavs, I need to be able to choose which audio is either cut in or heard at any given shot.
Is there any way to have control in multicam clips over which track of audio gets edited into the timeline, or even: that all tracks of audio get cut in? It's very important for the editors to be able to see waveform (which also disappears for some reason in the mixdown) and pick and choose which audio is heard?
I'm sure this might be a simple fix, but I cannot get my head around it for workflow purposes for my assistant editors. We need to use multicam, but this audio thing is driving all of us crazy. None of us can figure out how to have a multicam clip and use it with control over what audio is cut in.

Answer 1

True, but what I need to be able to do is have my multicam sequence in the source monitor, and cut into my working sequence with either just the audio I need from the sound guy's multi-channel WAV, OR cut in all the sound and from then I can just enable or disable what I need or don't need. But also be able to match back to the Multicam source from my working sequence.
I don't want to have to open the synced sequence, and razor blade the things I need and have to copy and paste into my working sequence in order to have the full spectrum of my multi-channel mono lav WAV files...with their waveforms visible.
Essentially, I want my Multicam clips to load in the source monitor, and the ability to cut them into the working sequence without it mixing down the audio into a single track with no visible waveform–which is what it is doing currently. Can I choose to edit in either ALL of the tracks of the WAV file along with the camera shot I want, or control which audio gets cut in?
