Filter in Scorecard for onsight, flash, etc

Hi webmaster, it would b egreat to be able to filter the scorecard for the different types of ascents, i.e. Onsight, flash, redpoint and so on. A simple user interface could be a checkbox next to the color keys below the chart - as standard, all types are checked, but the user could uncheck one ore several and hit a refresh button (to avoid multiple page reloads when unchecking more than one type). Any chance to get this? Cheers!
