unique progress bar for each anonymous user which resets after session close

Hi I have a feature request for Opigno. Normally when a public training is taken by any anonymous user, the progress bar shows 100% for all anonymous users after that. It should not be like that. The progress bar for each anonymous user should be unique for his session and should show his/her progress for that session. Say there are 100 anonymous users taking a training at a time. The progress bar for each user should be unique to that user which should show his/her progress. But as soon as the user closes the leaves the website by closing browser tab or browser, and opens the website again, the progress bar should be at zero again. Its just like loosing all progress after leaving the website. I think I'm clear in describing the feature. Thank you.
