Hi, Can we have substitutes when players are booked delayed. I substitute on yellow cards but don`t want to change a player 6 minutes into the game. Can we add, that it can be done at half time if a player is booked early on. Also maybe a don`t change if a player is booked after a certain time say 75 minutes as he is unlikely to get a second yellow. It would also be helpful if a player who is  not playing well or below 5 he can be substituted at a certain time in the game.
