title: Backbone possible to merge data?
body: <p>In a backbone application I am writing I need to combine 2 sets of data into one, </p>
  
  <p>I have the following in my initialise function for a view, </p>
  
  <pre><code>this.model.set('tasks', new Tasks(this.model.get('item_tasks')), {
          silent: true
  });
  
  
  this.model.set('subTasks', new Tasks(this.model.get('sub_item_tasks')), {  
           silent:true   
  });
  </code></pre>
  
  <p>Is there away I can merge these 2 pieces of data into one, to allow me to loop through?</p>
