(IMPORTANT)Can you consider extend Decay games to 1 game/2days when I hit 2 challengers in 1 account

I'm now currently flex challenger and Diamond 1 85LP in solo queue, school is about to start in September. It's even hard for me to keep playing 1 ranked game everyday. It took about an hour each game and if remake happens, It would take more. I'm afraid to play solo Q right now because once I hit master, it would take me more than 2 hours in ranked games EVERYDAY (and I do play normals with my friends), players would have no life if they decide to play more than one mode. I think it is really weird for games to become like that, I'm scared of gaining more elos even though I love to play ranked games.
