Is it possible to track labor cost in Projects without using OTL and not sending cost to GL using AD

Hi,

I would really appreciate, if some Projects and OTL guru can answer the following questions:

Background:

=========

We are using Project Costing and only interface Miscellanesous Transactions Cost to GL.

Users creates invoices in AP for Capitalized and CIP assets with Projects codes.

Transfer Supplier Cost (invoices) accounting to GL.

Create CIP/Capitalized Assets through Mass Additons in FA.  (Donot track CIP assets detail in PA)

Interface Supplier Cost  from AP to PA but donot transfer accounting for these transactions from PA to GL.

We do not use the interface labor cost functionality at this time. (Interface Cost to GL : "Interface Employee Labor Costs" option and Interface Contingent Worker Labor Costs are disabled).
