Shipping method drop-down instead of radio buttons?

[Artanis]

Hello!

My client asked me if it's possible to make drop-down shipping method list, instead of bunch of radio buttons.
I searched all over VM forums, but can't find answer. Can somebody give me a hint considering what corrections to make to \administrator\components\com_virtuemart\views\shipmentmethod\tmpl\default.php (as far as I understand, it's the part that generates list of shipment methods).

Best regards, Arthur
