You don't even need to do that - just filter on tournament games (click the little board icon between 'Game Id' and 'Opponent' column headings.
To the O.P. - what's wrong with the existing tournaments page? (The link is there just below the bar with your username in it at the top of the page) Click the links on the left of that page and you can see various views of tournaments you are in / have completed.
