Magento: product specfic designs through 'Custom Layout Update'

Question

If I want to control how each product is displayed (i.e. a custom design when specified) my first thought is to do this:

1. Create a custom view.phtml in template/catalog/product/my_view.phtml
2. Navigate in the admin to Product->Design->Custom Layout Update
3. Add this block:

---

<reference name="content">
    <action method="setTemplate">
        <template>catalog/product/view_print.phtml</template>
    </action>
</reference>

But the template is never loaded, only the default view.phtml. Is this the correct method? I need to be able to do this in the product settings.

Answer 1

Found the answer:

<reference name="product.info">
    <action method="setTemplate"><template>catalog/product/NEW_VIEW.phtml</template></action>
</reference>

Answer 2

Navigate in the admin to Product->Design->Custom Layout Update >
Add the below custom block. > It works for all the stores.

"<reference name="product.info">
       <block type="namespace_modulename/catalog_product_list_custom" 
   name="catalog.product.modulename" as="modulename" after="tierprices" 
   template="modulename/catalog/product/modulename.phtml"/>
</reference> "

Add the below code in view.phtml

<?php echo $this->getChildHtml('modulename'); ?>
