How do you offset MPS/MRP planned orders by a lead-time when loading interorg planned orders into an

We have multiple Orgs,  one supplies the others and it takes 1 week to transport the product to one of the Orgs but only a day to another.

In the 1 week lead-time Org, I set the lead time one an item, create a forecast and run MPS.  The MPS result shows suggested due dates with the same date as the forecast and suggested order dates one week ahead.

Next I load my MDS in the suppling org with the Interorg Planned Orders, but the MDS picks up the suggested due date instead of the order date, so it appears that there is no intransit lead-time.
