No, not for an audio track. I wouldn't drag the audio to a new track because you then lose your mixer settings, inserts etc.
instead, once audio has been recorded I would remove Thor from that track, open a new audio track and then reopen Thor in the new track. This way your settings are all preserved on the first track.
Edit: One thing I have noticed is that AudioBus does support apps that have multiple outputs, you just have to open the app up first before adding it to the input slot otherwise AudioBus will only see the main outputs. The only two apps I've found so far that support this feature is DrumJam and ThumbJam.
