How can we prevent "Non-Recoverable Tax" lines from being imported from Payables?

We are looking to have the same type of costing results in Fixed Assets for costs that are processed directly from AP to FA as would be processed from AP to PA to FA.  Currently, in the AP to FA flow,  the subledger "post accounting programs" definition does not bring "Non-Recoverable tax" over to FA.  Contrary to this, when an AP INvoice is charged to a project having Non-Recoverable tax, both the Item and NR Tax lines are imported to the Project and therefore are subsequently passed to FA.
