OK. Understood.
I'm not seeing any obvious way to reset the interaction after a SUCCESSFUL attempt. Only after an UNSUCCESSFUL attempt do you still see the Reset or Undo buttons.
Adobe has more or less designed this interaction to be similar to any other interactive object, such as a button or click box. The end result is that you can use it to trigger an action.
I agree it's a bit weird that it doesn't have the option to automatically display a Success caption, when it DOES have the option to display a Failure caption. Somebody missed the UI design boat on that one.
