Usually when I'm exporting stems, I'm grouping certain tracks into a single stem - ie all my strings tracks, Low percussion, etc etc..
It would be a huge time saver to be able to pack folders into my desired stem groups, and then check these folders in the "Tracks" dialog box in Export Stems so that these tracks could be stemmed together. Unfortunately if I use busses for this grouping, and use the "Channels" in Export stems, these exports do not include solo-safed sends, or master processing, only the audio coming off the bus. It seems just adding folders as options under "Tracks" would solve this grouping issue without requiring any additional routing in the console. Seeing that folders do show up as tracks in the Edit page, it seems odd that they are not "checkable" under tracks in "Export Stems".
