Hey there. I do not believe I am able to access 20 year dividend growth. The one thing I will say is 20 year is kind of an irrelevant metric. We are looking too long into the past and a lot of things can change over that timeframe. I am even a bit leery about 10 year dividend growth rates, as things can change substantially over a decade long timeframe.
We do have buybacks in the screener. If you go to dividends/buybacks section you'll notice stock buybacks. If the number is negative, the company has issued shares over the last year. If it is positive, that is the dollar amount of shares the company has bought back over the last year.
In terms of consecutive dividend increases, I can look into getting that added as well.
