Leaderboard to show progress instead of score

Hello,
Is it possible to have a leaderboard that would show a students progress as opposed to a number score?
Such as:

Johnny - Chapter 1
Betty - Chapter 4
Tommy - Chapter 2
Lilly - Chapter 4

If that is possible what would the code look like to update the leaderboard with the current experience “chapter” or string?

Thank you very much,
Jay
