How to reset scores on Friends Leaderboard

[Faith]

I didn't realise it at the time but the scores while playing modded are saved onto the main leaderboards, one of my friends and me have unfair times, one of them if real would have been top 5 pace so is there any way for us to reset these scores?
Or is it stored on the steam cloud and there isn't a way currently?

Did you ever find a solution to this?
