The Quizzes.Next FAQ states the following:
Are Quizzes.Next assessments included with Course Import in Canvas?
Common Cartridge and QTI imports allow users to select to import assessment content as Quizzes.Next format. This option is not available for other formats.
I don't see an option to import assessments as Quizzes.Next assessments when I use the Import Course Content > QTI and/or Import Course Content > Common Cartridge ... options. Is this feature exposed somewhere else or did I miss something obvious.
