Do you sell pizza? If so you have probably run into 1/2 & 1/2 pizza situations. SP-1 supports that and more. We support 1/2 & 1/2 as well as 1/4 and 1/3 pizzas (if you wish!).
Below is a screen shot showing a large supreme pizza. This pizza has extra sauce on the whole pizza.
We have taken salami OFF the first quarter and ADDED jalapeno to the first quarter. You can see the other three quarters as well.
