Scuf for Fortnite?

I ordered a scuf impact and I do not know how to change the paddles so I have perfect paddle-keybinds for fortnite! Could I get suggestions?

Play with the mouse and not such an idiotic pseudo - pro controller.

Sry but my personal goal is to become one of the best PS4 players and not such a stupid showman who plays with mouse who thinks he is better than PS4 player and then complains about PS4 auto aim and howls just because he was killed by one best example Ninja that's so pathetic.

But as a consolero nobody takes you seriously in eSports, on the PC the eSport happens after you are looking for.
