Is there a way to show inventory landed costs on a project?

We purchase stock materials directly for our projects. Often the materials come in with freight bills, which we historically have added as a separate line item & recognized as a separate account group to the project. However, we are looking at using landed costs to get the actual cost of an inventory item tied to that item - as sometimes we move that item into Free Stock. The question is, is there a report or clear way to show the landed cost variance just on project inventory? We would like to have a clear way to audit why materials are over budget if it is due to inbound inventory freight.
