Product Tabs And Vertical Menu <480Px

I have probably what I suspect is an easy question, so I shall prepare a 'doh!' in advance.

Were using the responsive template, the product tabs display on devices under <480px as an in-line vertical menu.

Above this, the product tabs display, as tabs.

My question is this, we too many tabs on many products, making the display of the tabs look clumsy, and float about, depending on the tab that is active/selected - but this only happens on devices <768px.

Is there a way to get the product tabs to be displayed as an in-line vertical menu (as currently the case on devices below 480px) to apply to all devices all the way to 768px?
