As in globally? You wouldn't be able to do so without essentially going through every PGCR that has ever been created looking for ToO matches, unfortunately. Fortunately, however, there are some groups here who have done just that. Hit up Steffwiz or VlakatafakatA, they are two users who have been mining that data and may be able to expose it in a more consumable format for your needs! The pivot that BNet exposes is very specific and not friendly to getting global sets of matches like that... but other sites that aggregate our data pivot it differently, and for the purpose of more global or team-based evaluations their data will be more useful than ours.
