title: WooCommerce function wc_get_template() modification
body: <p>Follow up to my previous question <a href="https://stackoverflow.com/questions/35405279/woocommerce-use-secondary-php-file-recalling-template">WooCommerce use Secondary PHP File (Recalling Template)</a></p>
  
  <p>The function below is a secondary add to cart function for my website which calls a secondary php template for grouped products, the problem is it will only work if the modified template is actually inside the woocommerce plugin templates folder.</p>
  
  <p>This is not good as any updates to woocommerce will delete my template. The problem is the third line "wc_get_template" this function will only work for me if the template is in the woocommerce plugins templates folder. When I need it to call the template from my child theme folder "custom-groups" folder.</p>
  
  <p>Does anyone know how I can make this function fetch the template from a folder other than the plugin templates folder?</p>
  
  <p>I have tried various techniques as you can see from my previous question but with no luck.</p>
  
  <p>When I try to add this custom template inside my woocommerce folders in my child theme the template doesn't work for some reason I think the problem is because it is not overwritting an original template....</p>
  
  <pre><code>function woocommerce_grouped_add_to_cart2() {
      global $product;
      wc_get_template( 'single-product/add-to-cart/grouped-simfree.php', array(
          'grouped_product'    =&gt; $product,
          'grouped_products'   =&gt; $product-&gt;get_children(),
          'quantites_required' =&gt; false
      ) );
  }
  
  function woo_simfree_product_tab_content() {
      woocommerce_grouped_add_to_cart2();
  } 
  </code></pre>
