Does Novel Games keep track of the datetime at which each star was obtained as well as datetime of when each leaderboard entry was submitted?

@Novel Games should keep track of not only the highest ranked result, but all results that the player did, and the player should be able to choose which result to use in mastery leaderboard and star count. This would allow users to remove their stars: https://www.novelgames.com/en/forums/how-do-you-remove-your-stars.2367
