Magento Quote Item object - how can I load item's options?

Question

While I know that I can just load Quote Item Options collection and filter it by item_id, I just can't wrap my mind around that Magento folks haven't added any _afterLoad or _loadOptions method to easily assign the options to an item, since there's already a _options, _optionsByCode properties...

to provide some example of what I'm doing:

// updated (forgot to actually load object
$item = Mage::getModel('sales/quote_item')->load($itemId);
$buyRequest = $item->getBuyRequest(); // almost empty, only qty is set

I want to know if there's some $item->loadOptions() method... or other native way to load options into an item

UPDATE

What I want to do: I want to load item object and use some native way to add its options to this loaded object.

Answer 1

I ended up using next piece of code

/** @var Mage_Sales_Model_Resource_Quote_Item_Option_Collection $options */
$options = Mage::getResourceModel('sales/quote_item_option_collection');
$options->addItemFilter($item->getId());
foreach ($options as $option) {
    $item->addOption($option);
}

While I understand that it doesn't answer my question directly, I think there's just no method of loading options inside quote item. So maybe someone will find the above piece of code useful.
