Rather incredible to me that this is not possible at this time.

In Tourney -> Results one can filter for years, months, dates, and last # of hands, hours, days, and months.

But nowhere is it possible to filter for the last #GAMES.

It should be embarrasing to HEM that sharkscope has more advanced search filters than HEM, since sharkscope can search for all of the above + last #GAMES.
