Out of the box this is not possible. You could probably do it with JavaScript.

I would recommend that you add an Add New Row toolbar button to the top of the list view and show a new row when it is clicked. Disable the Enable Add new row link button from the Settings 

 

Chuck this in a data label on your list view.  It’ll look strange though as the new row is the same colour as the first datarow.

var actionRow = $('tr.action-row');

var tableGrid = $('.grid-content-table tbody');

actionRow.detach();

tableGrid.prepend(actionRow);

Cheers
