Is there a simple way to create a BindingList wrapper (with projection), which would update as the original list updates?

For example, let's say I have a mutable list of numbers, and I want to represent them as hex strings in a ComboBox. Using this wrapper I could do something like this:

BindingList<int> numbers = data.GetNumbers();
comboBox.DataSource = Project(numbers, i => string.Format("{0:x}", i));

I could wrap the list into a new BindingList, handle all source events, update the list and fire these events again, but I feel that there is a simpler way already.
