Have a tag for pin location available that you can use either after holeing out or when removing the flag. That way you can add proximity to the hole data along with total number of feet in putts holed for the round.
can't this be done by tagging on of the "left over" tags. just tag it on the green @ the hole. come hole remove stroke and replace with the pin position ?

Maybe it would be the same Putter tag but you hold the tag for an extra second with an audible beep or double buzz that lets you know it recorded the info on pin location.
