Audio pass-through in FCP

I edit music videos. I import a stereo audio track (E.g. AAC 48/24 @320) and edit the video on top of it.

I'm looking for a way to share/export the video WITHOUT re-encoding the audio, like an audio pass-through option.

I also saved a custom setting in compressor with "Enable audio pass-through" checked, but when I send the project to Compressor it looks like FCP wants to compress the audio to 128kbps, and audio pass-through is greyed out. I can set the audio to 320, but my guess is that Compresso would re-compress the audio track.

So my actual workflow is to export the video without audio, open it back in Logic, and then save the video with audio directly from Logic, but that's just not very efficient.

The same way in Logic you don't mess with the video component and have advanced audio export settings, is there a way in Final Cut NOT to mess with the audio and just work with the video, then export the video with audio pass-through (no re-compression/encoding)?
