How to add per-variant attribute?

[VoilaNeighbor]

I want to derive Default for my custom enum. To do this, I'd like to write this:

#[derive(EnumKind)]
#[enum_kind(PainterKind, derive(Default))]
pub enum Painter {
	#[default]
	LinePainter,
	CirclePainter,
}

But that #[default] attribute is not on PainterKind, but on Painter. Can we add support for such derives?
