Two questions: Is there a start_date param for any endpoint? How to account for dividend price changes?

Hello I have two questions about the yfinance library.

1. Is there a general parameter passed to kwargs that I can set to get the start_date of any endpoint? For example we can set start_date and end_date to the history() method but can we set these to any method (e.g. institutional_holders, insider_purchases, upgrades_downgrades, etc)?
2. For the history() method, let's say I have a job that pulls GOOG daily data once per day with the start date set to the last date it ran. Say the job runs on 2/1/2020 --> then the next job runs on 2/2/2020 with the start_date set to 2/1. If there's a stock split on 2/2/2020 is there a way to have it automatically account for that? I was thinking by using the built-in cacheing maybe it can recognize splits in some way? If not it probably just makes sense to keep track of the splits in a database and apply basic logic to the tickers that had a split.

Thanks!
