Queen Vision

I just cannot do a Queen Scan in one step. Can anybody do this? I need 3 steps: First a short-range scan within a Knight's reach: All squares except the 8 of the Knight Circle. This needs sort of an inverse scan, which I find extremely difficult. Maybe this will improve with my X-Ray Training. What I can spot quite fast is the Queen Diamond, that is the short range 5x5 square without the 4 corners. Second a Rook Scan, third a Bishop Scan. My idea is to do these scans faster and faster until they merge to one single Queen Scan.
