Check "Use Default Value" for super attribute

Question

In the BO, when I go on a configurable product > associated products, I have this following block :

I want to check the checkbox "use default" for my configurable products.

When I load the product, I can't access to this super attribute :

$product = Mage::getModel('catalog/product')->load($product_id)->setStoreId($store_id);

I can access this variable with this code :

$productAttributeOptions = $product->getTypeInstance(true)->getConfigurableAttributesAsArray($product);

But now, I can't make any modification (I though make something like that : $product->setData($attr, false)->save();)

Someone have any idea ?
