I am using Mfg item definition trying to create a kit of parts of cut steel sections from stock material 
i set up my structure as 

provided part >> transform >> manufactured material >> kit of parts 

I would like to input stock length, that gets consumed by the transform and resulted in a new product that eventually gets bundled in a kit of parts. but I can only see on of the products in the kit of parts using the compute function in manage resulting product 

is there away to have the kit of parts taking the resulting products from all its children.
