Did you try pressing "Select multiple" and pressing checkboxes to select? Its no different to using ctrl to select multiple logs, but you don't need to press ctrl. As for filtering, I will look and write later. But its complicated, starting with question at what point do we filter out, don't even import some logs or import all and show only some. And from what logs show track records, filtered or all. And so on, all parts of r2la depend on assumption that all logs from folder are imported.
