I've searched within the DJI GO all and can't find such a feature - but I would really like to be able to record an audio track while I'm flying and have the option of adding the track to any video I may have recorded. This would be great for commenting on or narrating videos. Does such a feature exist and I just can't find it? If not, has it ever been discussed or requested? I know I can use a separate app or a separate device to record my audio and then add it to the video afterwards - but it would be so much more convenient to have the capability built into DJI GO and attached to my vid, my flight log or just available as a standalone MP3.
