In the example you can "group My own label" and get "My own label" put in the diagram where "loop" or "alt" would normally go.
What I'd like is a way to specify the first bracketized text that would appear after "group My own label" in the way that you would see if you did "loop My own label 2".
I already found you can put "else My own label 3" after a group and get additional braketized texts.
