Highlight shipment number after the record was loaded?

We recently migrated to V12 and I'm looking for a way to simply have the shipment number be re-highlighted after loading a record...that way when scanning in another shipment it would overwrite the current shipment number and load the next record... Right now in V12 if you scan into the field after a record was previously loaded, it will just append the next scanned value....

In X3 V6 it always re-highlighted the shipment number so you could keep scanning in shipment numbers to more efficiently jump around records.

Has anyone solved this issue yet?
