AutoCAD Civil 3D :: Location-based Compute Materials Corridor Shape?

I'd like to build a location-based quantity takeoff using compute materials (actually using a mix of QTO, composite volumes, and maybe parcels and bounded volumes but this question is specific to compute materials). I have been working on this technical challenge today and hope to have it solved by tomorrow morning.

I created a new 'Quantity Takeoff Criteria' and added materials for the items I'd like to takeoff with compute materials, such as the corridor shape volumes that are not well handled by QTO. So there are structure quantity types for materials Pave1, Base1, Curb, RW.Footing, Wall, and Barrier. But, when I return to Compute Materials I have the option to assign 1 object to each corridor shape named. Here is the problem, there are 36 pave objects named Pave1 and only 1 material Pave1.

The solution I tried is to go back and edit the code set styles to add a location prefix like 99CL1>M>06 to the link names - making 36 99CL1>*>**-Pave1 objects. But, apparently these are links and obviously not objects so the names did not go through to the compute materials objects list.

The next two approaches are: 1) Go back to the subassembly properties and edit the codeSetStyle with prefixes - I assume this means I'd need a distinct subassembly for each location, a unwieldy situation. 2) Create a specific material and shape pair for each location, for example 36 99CL1>*>**-Pave1 material and Pave1 shape pairs. An awkward workaround but preferable to defining a specific subassebly to each location.
