The Cut Layers Stacked function will allow you to cut and assemble the mats while they are still in the machine.
Stacked mats can only be cut from the Back, so it cannot include any cut-from-front elements, such as V-Grooves.
Stacked mats must use pre-cut matboard as the outside cannot be cut in Layers Stacked mode.
