Background images

Can use a point annotation with the X & Y coordinates as the label, then drag the annotation around to ID points on the image that can be used to create the custom polygons. (Speeds up the process).

Also for finding X/Y positions: Point Position is a freeware tool for PCs that will find X/Y coordinates on screen.
