It might be a good enhancement to allow the score keeper to select a player and press "re-enter" - which places that player back into the line up at their original position. The software would be smart enough to grey-out this selection for a player that did not start or that started and was still in the game. It would just be nice to have something quick for when the ump says Players 23, 45, 28 and 15 re-enter. I'm like "aaaaaaahhhhhhhh"

that is a challenge, not sure will be high on developers list as they have (rightly) avoided hard coding in paired substitutions to date..

. but i feel your pain.
