@kingman1979 Hi!
You could create a Collection for NL games, a Collection for AL games and a Collection for all games and that would give you a division breakdown and combined. It would not let you break out stats for games between divisions.
You can isolate stats for a single team using the teams filter. You could copy them out and aggregate them to separate division stats from games where teams from different divisions play each other. There is no multi-team filter at this time.
There is an export function that exports all the data from the collection as .csv files that can be opened in excel or sheets and you can manipulate the data there, for aggregation or printing or w/e you want.
EDIT: You can also exclude games from the result set by clicking the flags on the games page.
Thanks,
Jeremy
