P: Add a 14 line grid / Harmonic Armature overlay for the crop tool

The crop tool has several overlays, such as the rule of thirds, golden ratio etc., which can be cycled in and out with the "O" keyboard shortcut while in crop mode. 

This collection of overlays could become a much more advanced tool, if Adobe could provide one more overlay, the Harmonic Armature or 14-line grid, see below image.

This would introduce a basic template for dynamic symmetry, a long lost art of image design that most famous visual artworks are based on.

If the tool auto-resizes to the cropped canvas like the existing overlays do, the grid overlay would not need any variants, which are usually cycled with the SHIFT-O keyboard shortcut.

The coloring below is just for illustration, this could be a simple white line overlay as the others.
