So, keep the button sets Debra (they are working well for you and ensuring Storyline knows how you want these buttons to act)
Then yes, you are going to have to edit 24 individual buttons!
But....
Use the little known and often overlooked FORMAT PAINTER option. This will literally mean you only have to set up the SELECTED STATE on 2 buttons - 1 correct, 1 incorrect.
Then by DOUBLE CLICKING Format Painter, you can simply click the other radio buttons you want to be either correct or incorrect, and they will all magically have the same state applied!
I love Format Painter, and its often forgotten about, but for jobs like this its perfect.
