Thank you for your response. I have already read this guide: "How do I add all items or a random set from an item bank to a quiz in New Quizzes?"
However, this only let's me pull randomly from the entire bank. I do not want to pull randomly from the entire bank. In Classic quizzes, I was able to make a question group from a bank--and pull randomly from that. It is different, and the Classic quizzes way was better as it allowed more flexibility and less work for me.
Now, in New Quizzes, to make this work, I would have to make a small separate Item bank for every group of questions I want, and I do not want to do that.
When will the "question group" feature be added to New Quizzes?
