Screening for share dilution and buyback?

I am interested in distinguishing between companies that dilute shares (e.g., LSPD.TO and SIS.TO) from companies that buy back shares (e.g., DOO.TO, SJ.TO). Is there an easy way to screen for 1-year and 5-year share count changes in the screener? If not, would it be possible to add something like 1-year and 5-year buyback yield?
