Would like this function. To cover a fly caught in foul territory and/or the 4-5-or-6 fouls-and-you're-out rules.

You can have a pop fly caught in foul territory right now. It is marked as any other fly out, and when asked where the ball was hit, just touch an area in foul territory.

The 4/5/6 fouls and your out is something we do not specifically cover, but I believe it may just be considered a strikeout at that point, no?

I would agree. Count the fouls until the last and record the last foul as a swinging strike so that your pitch count is accurate.

At such time as notes are available or the ability to record additional data on batter peril at the plate, that should work.
