For logic like what you ask, it is usually best to use Process Flow. In the attached model (supply-chain-demo.fsm), I made the following 3D model:

Notice that the first Queue is not connected to the second. That is because as long as they are connected, the first Queue will simply send its items downstream.

Now, however, we need to find a way to move the items when we want. For this purpose, I made the following Process Flow:

The basic idea is that all inventory items are pushed to a list as soon as they arrive. The token that comes from the Replenish Control source waits for Queue2 to get to 20 items or less, and then tries to get 100 items from the list. Once the token has acquired up to 100 items, it then moves those items to the second queue, and goes back to waiting. In this way, the Process Flow defines the logic of the model, while the 3D objects define the layout.
