The closest you can get currently is use a custom Queue page instead of the default one, it doesn't support the %n in its title (replaced by number of songs) :
HBQueueButtons = QueueActions -EmptyList -ShuffleList
VBQueueWithButtons= (tabtitle=_"Queue",tabicon=gmb-song) _QueueList(songtree=1,cols="queuenumber titleaa",colwidth="queuenumber 20 titleaa 248",showbb=1,hscrollbar=0) HBQueueButtons
remove the HBQueueButtons from VBListCover
and replace QueueList in NBList by VBQueueWithButtons
