Exporting Timeline Audio Tracks as MXF Files

I'd like to export my project's timeline tracks as MXF files - a separate file for each of the 5 tracks that I have - because my sound editor can use them to set up a sound mix that has been pre-edited by me.
When I use the HD P2 Clip Exporter function, making sure to enable "export audio" and disable "export in 16bit/2ch", I get a nice MXF file which includes the usual Contents folder. In that folder, the Audio subfolder contains 8 MXF tracks, which seems to be the default and maximum for MXF(if you enable the 2ch option, you only get two tracks). I was hoping that 5 of these 8 tracks would be my five separate timeline tracks, because that would have made it easy to set up a sound mix with them. Unfortunately, the first two tracks are the complete mixed track, and there's nothing on the other 6 tracks (my tracks weren't locked or muted). Is there some way to do this?
 
I would create a new sequence for each of the five tracks, and copy the individual tracks to them. You can then export each of the sequences separately.
 
That would definitely work, but it's not as simple as the one-button version. I have a feeling that the problem is not with MXF, which is obviously designed to deliver up to 8 tracks, but with the P2 export aspect. It's designed, I guess, to export to a P2 card which can't accommodate 8 tracks, so it only sends two. Although, having said that, I have to wonder why P2 Exporter gives you the option to export as 2 channels or as all 8 tracks. I don't get it.

An alternative I've tried is to export each track as a PCM wave file. That does give me all 5 tracks, separate but in sync with the picture, and it only meant muting all but one track for each pass.

Thanks for your input.
