For a given week, it would be nice to have the ability to designate a specific backup player to swap out for a specific starter if their status is uncertain and they end up sitting the game out. You could argue that you don't want owners putting their teams on autopilot with settings like that, but this designation could be very specific and only apply to the current week. Plus, even sportsbooks are voiding some bets if a player is injured for a game, so it seems there is precedent for this. Thanks.
