Saving last question's answer without finishing the Quiz

Hello,

is there a way to save the answer to the last question of a quiz, without clicking either 'Leave blank and finish' or 'Finish' buttons?

The thing is that quizes on this site are configured to allow people to jump back and review previous answers.
Since users cannot save the last answer without finishing the quiz, they end up jumping back convinced that the last question is saved as soon as they click an answer option - and that's not the case.

They navigate to review previous questions and meanwhile the time limit is reached and the last question wasn't saved.

Would it make sense to have a button on this last page only to save that answer apart from the buttons to finish the test?...

thanks.
