How can I record many takes and keep them all?

How can guests record again to "fix their mistake"? Are all the audio files kept, or just the last recorded one?

Our audio recorder has two modes. A basic mode (last file only), where each retake replaces the previous one (so they only submit one take), and an advanced mode (keep all files) that keeps their multiple takes, allowing guests to build up their answer (and give you the outtakes that you want). You can have access to that in your Recording mode next to the record button.
