When you click File > Export and have chosen the name and format of your exported file, a dialog appears which presents you with the number of tracks you have on screen and allows you to map these as desired to each of up to 32 output channels (WAV, AIFF or OGG) or 8 output channels (FLAC). Currently there is no support for exporting multichannel files when using File > Export Multiple.
