Say I want to make a Rare Veggie Pizza from scratch. The current menu tells me if I have the required materials and how many pizzas I can make with it. The problem is that it requires cooking items from lower tiers. I find it a hassle making lower level stuff and then realizing I am missing stuff for the next tier and running off to TP to pick up more. To make a rare veggie pizza, I need to make Dough-> Cheese Pizza->Mushroom Pizza->Fancy Veggie Pizza->Super Veggie Pizza->Rare Veggie Pizza. I would like the menu to let me set which tier I want to start from and what product in the line I want to end up with and then tell me what I am missing. So for example, I want to make 10 Rare Veggie Pizzas. I click on Rare veggie pizza and type in 10 and I want to start off at mushroom pizzas. It will tell me what I need for 10 of them and what I am missing.
