IB/ToO Historical Rank/Flawless Stat

Every weekend players try to go 9-0 in Trials and make it to the Lighthouse and once a month they battle it out to reach Rank 5 in the Iron Banner and each time it resets starting you back at zero. It would be sweet if there was a historical stat (perhaps there is, I'm not sure) that kept track of your personal best for each character, so you could see how many times you hit rank 5 with Lord Saladin or what was your average trials passage progress across multiple weeks.
