Personas 3.0 SP1 - VA01 - Popup

Hi Experts,

In create sales order screen(VA01) -

When I click on the Sales Order Line item and hit the Ext Dtls button - a popup appears for external details. - here I am using only one field Mode of Transport. - See below screen shot.

Is there a way using Personas 3.0 SP1 - I can have the field somewhere in the main screen itself, so that I don't have to hit Ext Details button for multiple lines every time, just for that one field.

Note: there can be multiple line items in a sales order.

Thanks.
