Multicam Editing: 2 Person Interview Multiple Mics

Hey guys, I'm currently editing a multicamera interview with two people. They have their own seperate lavalier mics going into two seperate recorders. Two of them are close-ups of each person seperatly. One is a wirless lav going directly into one of the cameras. The other lav is going into a hand-held recorder seperate from camera tha's redcording the person. Then I have the third camera wich is a wide angle of both of them together which is the in camera mic which I won't use.

I know how to do multicam sequences with a single audio source but not two. I want to use the audio from each lavalier but not the wide angle camera and don't know how that would work. I also have to seperatly adjust the volume of each mic because for some reason there's like an echo-reverb effect when they both start talking at the same time. So I would like to fix that also if possible or keep it and ust the audio that I already adjusted.

Thanks for any help!
