Hopefully an easy one....

I hope I can ask this in a way that makes sense. We use a Summa DC5SX to print decals. Rather than use 2 colors on white or clear vinyl, we want to print with 1 color and the other color would be the vinyl. So...what is the easiest way to erase one object through all layers? Say I need to create a black square with a red triangle in the center. I'll create a black square and a red triangle separately, center the triangle on the square, and then I want to remove the triangle shape from both layers (because I'll have red vinyl underneath). It seems like there should be an option for selecting an object and delete that shape through all layers. I appreciate your help on this.
