Hello I was looking at this machine, but I am confused because I need it to dice veggies (like onion, tomatoes, peppers, etc.) and in the description and the answers to other customers it says that this in fact dice (cut in cubes). now saying that can you please tell me how do you accomplish that if the machine includes 4 shredding discs and 2 slicing disks but I dot see an attachment blade that cut a veggie into strips top later pass through the slicer disc to be sliced into cubes, I say this because I am familiar with other machines and that is the process or if you could please explain to me how is this accomplish. Thanks in advance.
