Something like that might be privately tracked.
The closest you might find is also from Micah, and it's shot rates relative to the league. For non-subscribers, he has only the current season heat maps available. Unfortunatley, I am not a subscriber, so I don't have previous season's heat maps.
Doesn't give you SH% for a particular area league-wide, but it does give you a specific player relative to the league in said area(s).
Not the same as SH%, but it's the closest that I know of. If I find something else, I can post it.
