Production of different products with its own order and PDS but with the same mold

An injection process produces with the same resource, same mold and same timetwo different products “A” and “B”, each product has its own PDS and order, the mold can produces 2 different products at the same time

Now APO PPDS proposes me to produce first the product "A" and when this finishes start producing "B", but both use the same mold

How can I set the system in order to propose to make 2 different products at the same time?
