Selecting Top Three Legends

It would be nice if we were able to rank our top three legends. With only around 7 seconds to pick a character, and just general distractions that may take place in my life, if gotten stuck with a character that I do not use because I'm going to the restroom or getting a drink before the game. It would be nice to have a top three setup so that if someone selects my top character it would automatically select my number 2 character, and, if by chance both my number one and two legends have been selected, I know that my third will be automatically picked if I don't select a character.
