How do I make leaderboards for multiple things?

Hi, 
I'm having an issue with leaderboards.
I am currently creating a game, in this game i have : multiple game modes, multiple difficulties and multiple themes. 

The thing is I would like to have a leaderboard for all these combinaisons.... But I can't create a bunch of leaderboards at the same time neither having a leaderboard with multiple columns...

One way could be to have a leaderboard type working like a SQL database where the first column is the User, then a bunch of column for each "dimension" (game mode, difficulty, theme) and the score. 

The only thing is we need to have the same score's data type for all combinaison, like for each game mode we can't have a game mode's score as a number and another game mode as a time.
