How to add announcement date to a custom report

I'm looking to add the most recent earnings announcement date to a custom screen report. I know there is the variable WeeksIntoQ which would give me the week of the report, but I'm looking for the specific date.

This date is captured in the stock snapshot under filings as the latest announcement date, so I know it exists in the database somewhere. Does anyone know the formula or variable I need to add to the screen report?

Thanks, Travis

LatestNewsDate should work.
