Unfortunately I don't think this is possible today. Handling of multiple tournaments only happens on the Stats tab, and the listing is strictly the list of players found in all of the tournaments. You'll probably have to generate this list yourself. If you have a lot of players and/or a lot of tournaments, the easiest way I can think of to do this is to add the "1st" column to the Stats tab (which lists the number of times this player has ranked 1st place), then sort by that column. If you double-click each player that ranked first and then scroll down to the "Tournaments" section, you can see the rankings the player had at every tournament in which they participated. It's pretty quick to glance through to find "1st place" rankings.
