Cubase Folder Group Track hierarchy

Now we can use folders as group tracks!
But what if I want to move one group folder into another and not to loose routings of first one? Is there a way?

Yes, you just move one one group folder into the other.

As soon as a track is moved into a group folder, the audio output (if available) is automatically routed to the input of this group folder. This also applies when moving a group folder into another group folder. However, the tracks contained in the moved group folder retain their routing.
