Can Checkbox sizes and spacing in quizzes be adjusted?

I have the same issue and questions as Graham, and haven't found a satisfactory solution. The text/answer options do not automatically align further to the right to accommodate a larger radio button. I, too, was wondering if there was a way to format the choices on a Slide Master, but unfortunately there is no placeholder for quiz choices. I learned to live with it when I used Quizmaker, so I'll continue to do so with Storyline 2. It's not a deal breaker, but I'm a bit of a nut when it comes to formatting, so the little things bother me. :-\
