Transpose line or pose brush for grease pencil

I think as a 2d drawing, bone rigging is just way too heavy,it is cumbersome right? For a 3d model you willing to deal with it because the model can be reuse all the time in your whole life. However, 2d not work that way, artist redraw each frame , we can't jump to object mode and add bone and select all stuff and bind and jump into pose mode and give up......🤣🤣🤣So please blender team, trust me, a zbrush like transpose line or blender sculpt tool that call pose brush should be make them work for grease pencil as soon as possible,that will be a game changer ever.
