how do i do this? is there a tutorial?
Go to the Correct and Incorrect feedback layers.
At the top-right you will see "Feedback Master" - click on "Edit".
Over on the left you will now see a Master.
Go to the top, right click and Duplicate Slide Master.
Play around and create what you want, also renaming it.
When you are ready, Close Master View, go back over to the right, and then select your (new) Master from the Dropdown.
Hope that helps - shout if you need anything clarified.
