At several in-person events, I’ve had an issue where players (instead of doing as instructed and using the initial email or phone number they set the team up with) will create a duplicate team. I won’t notice until the scoreboard is up and then I have two scores to try and combine (and the answered correctly number can’t be edited so that number will always be wrong from that point forward).
I would LOVE a way to just select two teams and combine them into one (with the most recently created team becoming the live team) that would automatically combine all of the totals and then remove the oldest team from the game.
