Teachers wishing to duplicate a question when on the Quiz edit page, currently, need to navigate to the (1) question bank, (2) find the category of the question, (3) click the duplicate button, (4) edit or just save the duplicated question, (5) go back to the quiz edit page, (6) choose to add a new question form the question bank, (7) go to the relevant category and (8) choose that previously duplicated question.

Which is a long "journy" for teachers.

I am suggesting to add a new button to the question action buttons on the quiz edit page, that duplicate the question + add it to the quiz, and leave the teacher the option to later go into the question and edit it.
