Cleaning stats

Hey all,
I don’t know if this feature already exists (if it does I didn’t find it) but I’m looking for an option to clean any of my visit or from another admin of my website, because all of them didn’t have the cookie not to be count in place. I think Piwik should search and delete automatically any IP address from his tables when we ask him not to take care about one IP, or delete recent visits from our IP when we establish the cookie

Moreover I think a similar option should be useful when we add some URL parameters to the black list : auto-clean pages with these parameters, or clean only the parameters not to lose visitors in the stats.
