Garmin S60: How to tell your watch you have reached your putt

Hi, 

I have just purchased a Garmin S60 and would like to know how you tell the watch when you have reached your shot into the green. i.e. I hit a fairway shot into the green or off a tee on a par 3. I just want the stats to record properly, I'm not bothered too much about recording actual putts and am happy with inputting these manually. 

I just want to know if there is a function to basically tell it you have reached your shot on the green. 

Thanks In advance
