Branching Scenario

Currently in branching question in a Branching Scenario content makes options are choosen without a submit button.

What I want is radio buttons as options and later submit button should be clicked to go to next branch.  Like in the attachement

Hey, 

I'm trying to create some content with the branching scenario. There are branching questions with one right and one wrong answer which will lead you to another question. Unfortunately now the first answer is always the right one because I was hoping that the answers can be mixed up automatically. Am I overlooking something or do I  have to rearrange the answers by myself? That would complicate the concept of the exercise a lot.

Thnaks in advance!

In the branching scenario, I’d like to be able to customize the interactive button text on the start and end screens from the authoring tool (vs having the know code).  Unless I missed it in the settings?  So, instead of “Start the Course,” I’d like to modify it as I might want this to be presented as something other than a course, like maybe for a game (e.g. “Enter the door”).  Same for the end scenario screen (modify “Restart the course” text).  Just having the default text say “Start” and “Restart” would be great if user modification isn’t an option.
