Paul, I already have the two geometries sharing the same vertex array. But some "decorations" to show a "picked state" are mutually exclusive. For example, showing the "picked" primitives subset as wireframe ( not filled) is not possible as the same primitives will be present as "filled" in the default set.
I suppose the sensible thing is to pick a decoration that can overlay the existing geometry (e.g all picked elements are outlined in a thick line) or are a different color with a larger polygon offset.
