Shipment V56I_DLNT_VIEW extension - new field

Hi people,

in shipment when I put deliveries I can see them in screen for planning:

I know that I can change layout here via icon. But is there any chance to add own "Z" field and fill it with value? If I show technical names:

there is a structure V56I_DLNT_VIEW. But I didn't find where to extend it and fill it with own value (I need to add an address of special partner from delivery).

Thank you.

David
