Limited quiz question types from Library
I would like to use some of the pretty Quiz templates from the Library, but... There are 11 quiz question types in the "built-in" or generic category--but the Library quiz questions only offer 3 or 4 question types each. If I mix Library questions with built-in questions, I'll have some serious style continuity issues, especially on feedback slides.
Am I missing something, or are the Library quiz questions actually that limited?
