Drawing Simple Shapes

It doesn’t seem possible at the moment so, this is a request: To be able to draw refined simple shapes such as triangles, squares, circles and arrows. I realize we have the free form pen/brush but, the ability to have defined shapes that can be resized willow all for a much more polished end product. An example would be reports which include images of inspections where the inspector uses a shape to highlight an area of the image.
