Shoulder Pavement Layer Quantities

[oageng09]

Hi all, 

Does Civil 3D allow you to differentiate between the carriageway and shoulder quantities ?

Reason being, Pav1 of the road and shoulder are calculated as the same thing but the materials are different. 

Do I have to create separate corridors to get the different quantities?

Or do I need to create assemblies from scratch and define different names?

Pave1 of shoulder is not the same as Pave1 of the Carriageway. 

Thanks, 

Regards
