edit penalty strokes after round has ended

Has anybody found a way to add/delete penalties from a score on a hole?  The garmin support agent only knew so much of course and tried their best to find answer but couldn't help.  They just said it can't be done.  I know how to add/delete total strokes on a hole after the round has ended and you save it and then sync, so i just do it that way.  But, if you make edits this way, the shot tracker doesn't update.  For example, if my current score shows 5 strokes on a hole (with 3 shots and 2 putts), if I go in and edit the score to say a "4" instead, then check the detail, it still shows 3 shots and 2 putts.  You would think it would be smart enough to know that the two don't add up.
