Hi Brian, the absence of the "Assign to Track" section is by design. The list of tracks in that section refer only to BIAB tracks which is why it is unnecessary for it to be included in the plugin's RealTracks Picker. To assign an RT to a particular track in the plugin, all you need to do is right-click on that track and choose Select -> RealTrack. This will open the RT Picker and place whichever RT you choose on the correct track. Hope this helps!
