Multicam-Clip: Mixing the sound

Hi, perhaps anyone of you has an idea:
I have a multicam-clip with only two separate cameras. Now I want to cut the visuals, but I want a mix of both audioterms all the time.
That means, I want to mix the two microfons of both cameras all the time. But when I cut the multicam-clip, I always have to decide, which audio I want.

I´m sure - anyone of you has an idea to turn around this problem... It might be easy I think, but at the moment I´m too :sick: ...

Thank you very much!

One way would be to put both clips in the storey line, get the audio levels how you want them, then export an audio only file, import this audio file back in to you project and use this as the audio for your multi cam.
