Select Similar Keyframes in Grease Pencil

I have noticed while animating in Blender that there were instances where I have similar looking frames and I only want to select those frames instead of the unique frames.

Often times this happens when I want to multiline adjust an iteration of a static pose that has been copy pasted multiple times on the timeline. Instead I have to delete all the duplicate frames, do the edit, and then copy-paste that version.

Also if it isn't too difficult to implement using the existing code for interpolation, usually if you are making 2 static poses you don't make the same strokes, so it would be better to judge similar keyframes by distance of the verts from the selected frame to ensure that the keyframe similarity is by the visual and not the stroke information.
