Feedback and Attempt settings

I am working on a 50-question quiz. We started out with feedback for each question, but the process owner would now like to change that to no feedback. Is there a setting I can chagne somewhere so that all questions get the same setting at once? It seems cumbersome to go change each question individually.

Also, when I change the feedback option to None, the number of Attempts for the question switches from a list of options to the fixed choice of 1 attempt. I want the user to have the option of multiple attempts. If I change to 5 attempts in the Quiz Properties, will that override the fixed 1, even if the display for each question does not?

Thanks so much,
