Double Stamp tool (for stamp and shadow)

I think its a pretty popular technique to use the same stamp for the shadow of the stamp. It would save a ton of time to preset an offset, shadow stamp opacity, scale, etc then just click once and get both.

Perhaps when you place the double stamp they are grouped or linked in some way to make it easy to edit them after they are initially placed. Certainly easier then locating a matching shadow to stamp in lists of hundreds of assets.
