Force Leads Reports

Either give us the ability to build our own filter or make these changes to one of the Leads set filters: only leads and not current clients and (1) the date displayed is the date the person (not any partner or system updates) last interacted with the website. The current filter and results give the impression that there was recent activity/interest by the person but it was actually a registered opportunity update that brought them to the top of the results. If is there another place in Force that only provides prospect activity for the website, please direct me there.
