Grid Model - How to add a TransView field when Grid Model is ShipDtl

I created a column in TransView to scan Order-Line-Release. On Customer Shipment Entry, I want to add this column to the Ship Details Grid. The Grid’s
model is bound to ShipDtl.

I added TransView.ScanOrder to the Grid and created an event to trigger after the column changed. Unfortunately, the Event isn’t triggered in the Grid. Of course, I can get the Event to fire if I’m outside the grid.

I don’t want to create a persistent column in ShipDtl for a temporary value. Am I missing a property in the configuration for TransView.ScanOrder in the grid or am I trying to do something that cannot be done without creating a View with a mix of TransView and ShipDtl?
