Is there a way for me to go back to a game from a few days ago, and change a hit to a error. I marked it as a single, and if was a error. Thanks

We have a 15 man roster and only 9 hit, when the coach quickly adds a sub batter in how do I sub him in without deleting the player he came in for stats? The first game I did I just held on his name and switched with the batter he was coming in for but the previous at bats gave the new batter credit...
