I use a lot of audio routing and virtual audio devices (using an app called Loopback). None of my other physical and virtual audio units show up as options to select in "Audio Routing". The only device that does show up is the default audio unit set at the operating system level. All of my audio units (both virtual and physical) should be displayed and available to be selected, not just the default audio unit.

You are on a Mac, right?
I don't know why but it seems that universal apps like Stage Traxx are not able to choose an audio device. I tried lots of different approaches (those that work on iOS and those that work on Mac for native apps) and I can list all available devices but I can not activate them.
So bottom line: only the current selected system audio device can be used to output sound. So make sure you setup the device you want to use in the Mac control panel. It that device is a multichannel device, you will be able to route to different outputs.
EDIT: Even if device selection would work, you would not be able to route audio to different audio devices at the same time. Not even Logic can do that. You can only work around this by creating an aggregate audio device. But this approach also works currently you just need to select that device as the system output device.
I use numerous apps that allow me to select a particular audio unit, virtual or otherwise. I'm not trying to select multiple audio outs — just one, and I would rather not have to keep changing my default audio unit just to run Stage Traxx through my desired audio unit.
I can get by as-is, but it's a source of irritation having to keep changing my default audio out in the system prefs just to make sure that Stage Traxx uses my desired audio unit.
I find it hard to believe that from a programmatic standpoint that you can't access all of the available audio units and not just the default setting. Literally all the other audio-based apps I use have equal access to all my virtual and physical audio devices — and allows me to choose which one I wish to use.
This is EXTREMELY handy as a performer both from a live standpoint and live streaming online where my audio routing is a bit more involved.
Well, I was not able to make it work. You will have to live with the system audio output.
Wait till your running 64 channels of Dante, and 48 of USB just to the one mixing desk from the Mac, on top of all the usual outputs lol -- it can get confusing
peter So this would probably shut down another feature request of mine:
I'd love to be able to have a "multitrack" session for each song, where one track would have your standard stereo backing track, but would love to have a separate click track that I could send to a different source — or synchronize with an external click of some sorts. Bottom line, I'd love to be able to maintain a stereo backing track and a separate track/send that has the click.

Sorry to keep going on this thread, knowing that you can't make it work. But this would basically break your app's multitrack/aux functionality. The aux is the same channel as the main output, and that goes against the documentation which says you could route the aux/click to your drummer...but that's not the case. The aux and main output (presently) are unable to be differently routed.
I know you are having a hard time getting this to work, but this seems like something a lot of people that use backing tracks would be looking for this sort of functionality. I know I am as well as the band I'm in.
You can route tracks to different outputs. But you need to have a mulitchannel audio interface. Select that as the main audio output in MacOS and then you can route tracks to different outputs.
