TWO product on one maschine

Hay,

I wonder if I could make two different products on one machine. I would like have one feeder and then goes into a Milling Machine, where you can make cylinder with two different diameters. It would be great if you can choose a different pattern of making it.
For example, in first try I want to have 1 cylinders of 50Φ and then 3 cylinders of 40Φ and then in next simulation I would like 4 cylinders of 50Φ and 1 cylinders of 40 Φ.
Any recommendation how to make that.

For any help I would be very grateful.

Sincerely, David

Hey,
there could be two feeders but it must be one maschine.
