Historical League - Don't import prior stats
 

I'm trying to play a historical league, but I'd like to start in 1900, but I don't want to import all of the stats from 1871-1899. In other words, is there a way to have all single season, career, and individual stats be erased prior to 1900 so that only games after 1900 will be recorded for season and career records? I have tried several options and searched this forum for an answer but can't find one. Can anyone help?
