sorry, there's no command for that.
the popular method around it is simply to build a macro to advance through the stages, and provide an adequately timed pause to quickly double-click your ingredients.
<<<editorial warning>>>
Personally, I see little use in crafting macros, with proper window placement I can fly through the crafting process when I'm just practicing. In fact, I've had macros that have magically consumed ingredients without actually executing the crafting process or giving experience. So, use them at your own risk.
