Is anybody using Sage 100 Contractor to track California Sales Tax?

Currently we pay sales tax on all of our materials purchases.  Some of our projects are lump-sum quoted projects (which means we have no sales tax liability).  Other projects are marked up Time & Materials (which means we owe sales tax for the marked up portion of materials).  

Does Sage 100 Contractor provide a way to automatically track the sales tax paid according to the type of contract that the materials were charged to?
