Easel? Make duplicate work pieces. In piece A, use the largest bit as the rough bit and the next largest as detail but. In piece B, use the detail bit from piece A as the rough bit and the next smallest as detail. Then run the rough from A, detail from A and then detail only from B.
You could cascade as many bits as you want, in theory.
This has been covered here so you may want to look at old threads about it.
