Audio monitoring and stereo recording 6D

[nanopast]

Hi, i recently upgraded from the 60D to the 6D and i'm in trouble because ML doesn't have the same audio features.
In the 60D i could choose to record in stereo channels, using one channel for the external mic and the other for the internal, a feature that really worked for me (I work on the press).
Could someone make that feature for future releases for 6D? I'd really appreciate that,
Thanks!
