I often have to take screenshots starting from top-left corner of my screen. I used another product that had below recommended Extension included.
Recommendation: To select a region you press-and-hold the mouse button. This could be extended to automatically capture the region between top-left-corner of your screen and the mouse-position if you perform a mouse-click instead of press-and-hold. In this case you can still manually capture a region using press-and-hold or just click if you want to capture from top-left as starting-position.
