title: Add a row or column to selection Excel
body: <p>This is probably super simple but If I already have a selection how can I add the next row without know necessarily what the next one is?</p>
  
  <p><strong>EDIT</strong>
  For example if I have the input range "D1:D8" how can I add in the next row, ie "D1:D9" without putting in "D1:D9".</p>
