No output and reverb bus available in mixer

I have no outputbus and reverbbus available in the Dorico mixer. In this post you can read how I have setup my score:

In a nutshell: I have changed the VST from Halion to Garitan before I have added my first player.

How can I add the Outputbus and Reverbbus manually without setting up a new project?

Edit post: for the time being I’ve setup a complete new project now without removing the first Halion Instance. Now I have an output and reverb bus.

This is a known issue at the moment, I’m afraid: until the first player is added to the project, no routing data is set up. Once you have added at least one player, you are then free to completely change the VST instruments etc. that are in use.
