Fangraphs Data Pull Request

Hello,
Is there a way to request a fangraph split stats as a pybaseball module? Based on my understanding of the code, the fangraph functions batting_stats and pitching_stats only apply to 'standard' batting and fielding data. Can this be created for the datapoints reflected in this output

I also could not find the code referenced from the 'pitching_stats' method, only the doc. Is there a way to view the underlying code? I could try to create something comparable to scrape from Fangraphs - although it will likely take a bit of trial and error! Heavy on the latter part!
