Module upgrade

Filtering module upgrade. In present it filters by Make -> Year -> Model -> Engine and at the engine selection it alow only one by one selection. I need to upgrade in order to alow me selection of multiple engine types at a time, and also to alow selecting all engine types by one click, and then add to the list. So, multiple selections and all engine types selections from the dropdown menu. Also, if posible when switching the language in prestashop also the filtering module to switch to other languages. If posible. I can make those translations if needed, now i am using 9 languages.
