Embed multistream audio

Hi folks,

I have a project with a delivery spec I'm not familiar with. I need to embed a 5.1 surroud sound mix and a stereo mix into the same prores file as a single stream.

In the past for 5.1, I just did a mono track for each channel with the proper pans and mapping in the track mixer and double checked the mapping in the export window. Would I just do the same thing and add the additional stereo tracks I need?
