ballparks

[Edward]

Shaun, can you add more options to the default ballparks. Almost every ball park has gone over at least 3 significant changes in its history that would greatly effect stats.

e.g.
Forbes Field 1909-1924, 1925-1947, 1948-1970
Yankee Stadium 1923-1927, 1928 -1936, 1937 - 1975, 1976 -1987, 1988-Present

thank you for your consideration.
