[FFmpeg-user] Is it possible to set a "this is a dolby E stream" flag to specific Audio Streams in a IMX D-10 MXF File?

I am using FFmpeg for generating a D-10 file with 8ch audio (16bit).
Typicall the Audio is always PCM but sometimes some dualchannels are is 
a Dolby-E pair.

Is it possible to set a metadata flag for Audio channels to give the 
decoder which opens the final MXF the information that it should decode 
Dolby E and not PCM on e.g Ch5 and Ch6?

Example D10 file with Dolby E is

1 stream video (0:0)
1 stream audio with 8ch (0:1):
ch1 PCM
ch2 PCM
ch3 PCM
ch4 PCM
ch5 Dolby E (encoded as PCM), needs  a "Dolby E"-flag
ch6 Dolby E (encoded as PCM), needs  a "Dolby E"-flag
ch7 PCM
ch8 PCM

Any hints and tipps are welcome :)
