Model Number to Options

I need to add a different model number for the options. Is there any extension to do this ?

e.g.

Camera with model number "000-0"
Camera with color red, model number "000-1"
Camera with color blue, model number "000-2"

Thanks !!

Options boost does this and adds more useful stuff too. Great mod - http://www.opencart.com/index.php?route ... on_id=6804
