In Magento, how do I change an API attribute to show on the base API products call, rather than for a single resource only?
<p>In the Magento admin, when you are selecting which API attributes appear in the API call for products (System -> Web Services -> REST Attributes), some attributes have an asterisk by them. The asterisk means that those attributes are only returned when you request a single product (something like <code>/api/rest/products/2262</code>, instead of <code>/api/rest/products</code>).</p>

<p>I need one of those attributes to be shown in the multi-product request. This will save hundreds of API calls. So how do I change an attribute (for example Product URL) to no longer be "returned for a single resources only", but instead show up when I hit the base call? (<code>/api/rest/products</code>)</p>
