+1 for the idea! It'd be warmly welcomed to get box scores in the spreadsheet/txt download, too.
For the shot selection idea, I think following 2K's approach would be the most useful. Essentially it would divide "midrange left" into midrange left corner + midrange left wing, etc.. So maybe a more complete list of shot selection categories would be:
Rim - left
Rim - center
Rim - right
Midrange - left corner
Midrange - left wing
Midrange - center
Midrange - right wing
Midrange - right corner
3FG - left corner
3FG - left wing
3FG - center
3FG - right wing
3FG - right corner
