Vital's Output Channel Setting

Hi Everyone:
Does anyone know’s how to set the output channel in standalone Vital?
The only setting available is the output device, after that can’t find where to select the output channels for that device, or any where to route the signal.
Since The “default” output1-2 is not my speaker output of my interface, so I can’t get any outputs now.
It should be a pretty essential setting for any audio app, like the arturia’s setting shows here.
However I can’t find in vital anywhere

You can’t do that directly. You need to find a lightweight plugin host for your OS for that.
