Record more than 2 audio tracks at the same time without splite to another file

I know that I can record the third track in a Wav file but what I want is record 3 audio without slipt to another files.

I know that Action! can enable recording the third audio device track into an audio file,
but what I want is to record 3 audio device tracks at the same time and save them into the same video file.
It is possible to make this feature?
Because it would be more convenient for editing videos.
