I only have experience with the H4. but from what I remember playing around with the demo set at citymusic, configuring to record individual mono .wavs on the sd is not possible. you would still have to split them in DAW. which I assume you would want to have such control for "panning" (narrower image) etc.
should be possible too if you configure your DAW to record audio inputs 1 + 2 separately as 2 monos.
