Grease Pencil for Max? Like Blender!

Hey talented people!

Why no script to draw in 3ds max viewport to aid Previs/Storyboard planning?

Look at the grease pencil tool for Blender!!

Is there something like this for 3ds max?! But even a simple draw tool will be good to know.

Anyone has anything? Please share!

Thanks!
