Fix "Flatten group clip" to keep audio in tact
Multicam with Audio
Do not downmix audio - option to keep audio tracks as source so multi mics can be chosen - as expected
When flattening group clips - include all audio tracks, in original form - currently audio tracks are removed / or at most include channel 1+2.

If I get your request correctly, we already have these options in Premiere.
You can create multicams with the audio sequence settings set to "All Cameras"
All Cameras uses all audio channels in the source clips. This setting is similar to the Camera 1 setting. Only the video portion of the source sequence is multicam-enabled. Audio-follows-video is not supported for this setting. All audio is unmuted (up to 32 channels). The number of unmuted channels of source audio determines the number of active output channels of the sequence.
