allocating landed cost on drop shipments

my customer wants to allocate landed cost (freight, duty) to a posted sales invoice for a drop shipment (potentially indirectly via a posted purchase invoice); however, Landed Cost excludes drop shipment entries; has anyone made a mod or is aware of a workaround for this ? thanks

Expanded Solutions ( out of Atlanta (?) has a Landed Cost add-on that might suit your needs. Try contacting Tommy Madsen.

Just an FYI - We contacted a bunch of references when we were considering the use of a different add-on from ExpantIT (having been badly burned by someone else). Although we did not end up purchasing from him, all of the people we called spoke highly of Tommy. They liked the add-on and his support was quite good. Rick
