title: Insert new item at top of list view when ListCollectionView.CustomSort set
body: <p>I have a list view with custom sorter (set by ListCollectionView.CustomSort property), however I would like to insert new items at the top of list view. How can I suppress CustomSort?</p>
  
  <p>I have an idea to tune my sort logic, so newly added item will be the first one, however this solution stinks a little bit.</p>
