I initially creating a case for this but it was suggested I create feature idea instead. So currently, you can duplicate a quiz created in the new quiz tool. When you duplicate an item, the word "copy" is added to the title. You can edit the title from the assignment index page but the title on the Build tab will NOT update. Recently I migrated several quizzes for instructor and found the workflow of setting up the first quiz with the desired settings and then duplicating this quiz from the assignment index page to be very useful. However, when I update the title after duplicating, it doesn't update the title on build screen of the quiz. This was extremely confusing. This is not mentioned in the guide linked below as well.
