title: sonata_type_collection set default number of rows on page load
body: <p>I make use of the sonata_type_collection for order rows inside my order. As soon as I create a new order I can click a button to add an order row.</p>
  
  <p>Is it possible to change it to automatically show 5 rows on page load instead of clicking the button for the first row and so on?</p>
  
  <p>I guess it is possible to make a JavaScript script for on page load to 'click' the <kbd>Add New</kbd> row button 5 times.</p>
