add button to review all questions at the end of an exam

Hi,

It would be great if you could add a button/option to review all questions/explanations when finished with an exam. This option is not easily visible and I am having a hard time finding a way to review all questions that I took in a recent practice exam. Currently, it seems like there is only a way to review marked question rather than review all questions within an exam set once the exam has been submitted.
