Support changing dual icon as well as @icon

I'm aware we can dynamically change icons:

@icon:largeicons,VIEW=LargeIcons @icon:smallicons,VIEW=SmallIcons @icon:listmode,VIEW=List @icon:powermode,VIEW=Power @icon:thumbnails,VIEW=Thumbnails @icon:tile,VIEW=Tiles @icon:detailsmode,VIEW=Details

Could we also get the ability to change the second/hover icon too?


Thanks!
