Move drawing out of centre

I am viewing architectural drawings in Sumatra, it is superior to many other solutions out there for its quick load and quick scroll of even heavy large architectural and engineering drawings.

Sometimes I prefer to move the drawing out of centre, for example I want to move the corner of the drawing to the center of the viewing window. However Sumatra keeps the center of the drawing locked to the center of the viewing window.

Is there any setting I can change in order to allow me to “unstick” the drawing from the center of the viewing window?
