Duplicate Grease Pencil Layer Group

Edit: This feature was supposed to be added But hasn't as of Blender 5.2. Either way i made a Add on that Does this and more. Try it for free on the Extension platform: extensions.blender.org/add-ons/gp-select/

Some times you have a layer group that's a bunch of parts. As of now you have to duplicate each individual layer.

I wish you could just duplicate the whole group
