Unable to edit shipment stop's Manager layout

Summary:

On Shipment level, we have Shipment Stops tab wherein we have details about stop Actual and Planned timings

We have a column for Actual Arrival at a stop but not for Actual Departure at a stop so user has to move inside that stop and see the actual departure

So requirement is to have Actual Departure timings of the stop at Shipment Stop screen level.

When I go for editing it in manager layout of the shipment it says "Uneditable field" so that cannot be edited

Is there any workaround to have that at Shipment stop front level?
