I hope this is the right category for this. It seems like the best to me.

Suggestion
Allow Lahman-style imports for leagues not abbreviated as "AL" or "NL".

Reason
The primary reason is that this would create an awesome new ability to plan out fictional leagues in advance. For instance, one could create a Lahman-like layout of the teams.csv file with different teams and league structures.

There would be some limitations, of course. This could not be expected to account for teams that moved from other leagues, league beginnings and endings, or league designations moving from minor to major or anything like that (although perhaps the game could use a second csv for other league attributes, like rule changes.

This would be a huge boost for those like me who like to sim out histories but want some nuance and team movement in the histories without having to stop constantly and reset it.

A secondary thing this would help with is inclusion of leagues like the Federal League or some pre-1900 major leagues.

Priority
Medium.
