Removing and adding in game

Hello, so I like to do openings on nulls brawl, but the powerpoint at the end of the item, its like almost in every box when you get 4 or 5 items. I want to do like in the normal brawl stars that could have the boxes rarely that gets powerpoints, so thats why i want you to remove. Adding in game, i want you guys to add like gears and gear tokens in boxes so it will be not strange to think that, it has gears and gear tokens in brawlers but not in boxes.
Bye!
