Is the answer for A meant to be Lead Float? If the question here is asking for how to take two orders called from unique packages that will call at the same time, but ensure they generate with staggered start and end dates, the initial and subs buffer, aka lead and subs float, can be used on the maintenance packages to manipulate the order dates. Hierarchy will supress one order, rather than stagger.
