I can do it, but i'd first wanna see my PR merged, check it out #26.
Looks like @jamesmontemagno is busy, I hope he gets to do some maintenance around here a bit.

You can subclass ObservableRangeCollection and just add a new method:

       //-------------------------------------------------------------
        public void InsertRange(int index, IEnumerable<T> collection)
        //-------------------------------------------------------------
        {
            CheckReentrancy();

            int currentIndex = index;
            var changedItems = collection is List<T> ? (List<T>)collection : new List<T>(collection);
            foreach (var i in changedItems)
            {
                Items.Insert(currentIndex, i);
                currentIndex++;
            }
            OnPropertyChanged(new PropertyChangedEventArgs("Count"));
            OnPropertyChanged(new PropertyChangedEventArgs("Item[]"));
            OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, changedItems, index));
        }
