Possibility to prevent further actions of the Action Builder / Messages with optional interaction by the user

With the ability displaying a message from the Action Builder it would be nice to be able to let the user make choices, means the message box should have an option to display buttons with custom text and configurable values stored at a custom variable. This would give the ability to interact with the outcome of the pressed button, like aborting further actions or get an input (pre-defined value) and take further actions based on the user choice.

So the steps could be setting a variable at the Action Builder like varButtonValue set to ""
Setup the message dialog and define buttons, check- or radio-boxes each with a value to be stored at a selectable variable like the varButtonValue
Setup further actions with conditional checks by the value of the varButtonValue

Just to explain, what I think would be a great enhancement. Of course the step with storing the value manually to a variable can be made obsolete, if the message itself would hold the button value and the condition would be able to read which button was pressed/clicked.
