Ability for Candidates to review their answers at any point in an interview, not just at the end

After answering a few questions, but not finishing the entire interview, a candidate may wish to review and re-record their earlier answers. I think rather than forcing the candidate to wait till the entire interview is finished before they can review the answers, surely a simple button that allows candidates to see where they are up to in the interview, and the answers they have given, would be better.
