Limit what products can be picked up from assemblers while allowing others.

Ability to limit what items a truck delivers to an assembly. For example I have 3 assemblies, 1 making contruction parts and the other making construction parts and construction parts 2 but I don't want the trucks stealing the construction part 1 from other locations to give to the assembly making construction parts 2, I still need the trucks to deliver the other parts like wood and iron however
