At the moment there is not. However I am planning to update this application further down the line, and add a way to delete entries. In the meantime, you can send me your leaderboard details and the entry to delete if you want to delete and entry.
Hey, just wanted to let you know, I updated this tool. You can now migrate your old leaderboards (if you had any), to this new version of the tool and have more control over your leaderboards.
