Garmin R50 HTH feature request(s)

I know there have been similar requests, I'm just adding on / combining my request(s).

-On the R50 could a feature be added that would allow the ability to select the club being used in HTH?   
          I've noticed that in the driving range within the R50, numbers look close to what I would expect (when playing around with the elevation). 
          However, when I'm using HTH, distances vary greatly to expected.

               - I've had my R50 unit for over a year.
               - Not using a third-party software. Just the R50 unit itself.
               - Elevation, and weather conditions are the same as what is being used in the driving range feature while receiving expected results.
                      If elevation is set at 1,000 ft (approx. elevation where I live), distances are still up to 60% less than expected (full swing driver). 
                      When the elevation is set to 10,000 ft, distances are still less than expected but are somewhat reasonable to what I would expect at my elevation.
               - Yes, I've followed all recommended setup protocol.

      **One thing that I've found that helped slightly in the last week.  There is a door with a window directly behind me in the building I'm using the R50 unit.
         It is not facing the sun, but I've found that when I placed a curtain over the window, it reduced some of the variation experienced in HTH.
                 - This is just speculation, but I suspect that if the area behind the golfer (or a window/door) is the same color as the ball being used it could affect
                    the ability of the R50 cameras/sensors to see/track the ball.

-The ability to play/download 9 holes.
          When i have friends over, 18 holes can take upwards to 4 hours to complete.
               - If 9 holes could be selected/played, it would be greatly appreciated.
               - This would allow R50 owners to have friends over allowing for a less time commitment

I realize there have been great improvements in the last year with the R50 software, I appreciate the Garmin teams continued support.  I'm just trying to see if there would be a way to match the experience seen in the Driving range within the R50.
