Global setting of default points for questions, other than 10 (Captivate's default)

When we create a quizz slide, by default it's worth 10 points. Which is a problem for me when I have several good answers and a partial score, because 10 is not a practical number to divide points.

I'd like to set somewhere that each quizz slide I create is worth 60 points (instead of 10) : is it possible ?

I don't find in in the global quizz settings.

Or can we process slide properties in bulk (and pick all relevant questions and bulk assign the number of points) ?

Thanks a lot.
