Ultimate Statistics for PalmOS

We've been using this great program on our mixed club
team (WMD from Cambridge, MA) for two years now, and
the captains have found it very useful for tracking
performance. One request we have, though, is the
ability to see the number of turnovers each player has,
while in the subs dialog, rather than number of points
played. This is because we've noticed at high-level
club play, the number of throwaways is more important
in deciding who should go in and who shouldn't, than is
the number of points they may have played. It's a
minor modification--would it be easy for an amateur
programmer to handle the source modifications?

Many thanks.
