How to distinguish between "Make from" and "Used to make" relations in Product Structure Explorer?

We have a casting that is machined in 3 steps. This means that the "intermediate" part has a "make from" relation which is the base part and a "used to make" relation to the final part. However, in the Product Structure explorer, there is no distinction between these 2 relations. There is only a Make From = TRUE and CAD Dependency Of = TRUE. 

Is there a way to make this distinction?
