Microsoft Learn Challenge Leaderboard

Recently I have been doing Microsoft Learn Challenges and during the issuing of rewards, it becomes difficult to determine the top participants in the challenge according to the time one completed the challenge as the leaderboard is arranged alphabetically. 

Instead of having the leaderboard arrangement be in an alphabetical order, what if it is according to the earliest to the latest to finish the challenge to make it easy and fair for the top earliest participants to be rewarded?
