When editing with "responsive mode" you can show/hide elements in "tablet" and "mobile" view. Is there any way (apart from custom CSS) to show/hide them for "default" view as wall? In other words - how to "replace" e.g. slider module that's on "default" view with another module (e.g. another slider or image or anything) that will be visible only in a selected mobile view, since you cannot drag&drop modules in responsive mode...?
