The "Go to" workflow action adds a link to another workflow action already in your workflow so that you don't need to duplicate the same workflow actions for different branches.
A dotted line arrow displays the hierarchical path leading to the action you selected from the list.
You can't add another Go to action below a Go to action. Validation prevents infinite loops. You can modify the "Go to" action by selecting it. You can change or delete the selected action. You can't delete a workflow action referenced by any "Go to" actions, you first must remove the workflow action from the Go to action before you can delete it.
