A bus map based on a new Work Unit is used when a new Cue is created.
It can be configured in the [Bus Map Based on a New Work Unit] of the Inspector that is displayed when you select "User Settings."
This bus map is applied when a Cue is created in the terminal (command line).

You can also right-click on a Cue configuration bus map and select [Set to Bus Map Based on a New Work Unit] from the context menu.
