Is there any way to break apart compound audio clips in Final Cut?

I'm pretty new to Final Cut, so I need a little help. I recorded some audio and video from a capture card, as well as a microphone in OBS. I set OBS to record the audio in separate channels. When I open the exported clip in Final Cut, it recognizes the audio as "multichannel audio." In going over the footage, I noticed that the sound from the capture card did not sync with the sound from the microphone. Is there any way to separate the channels in a multichannel audio track in final cut, that way I can drag the clip around and sync it? I think I may have to adjust the settings in OBS in the future, but I would like to be able to edit the footage I already have.
