Is it possible to have only the selected items in a Multiple-Selection List Box be displayed? Obviously there would need to be some sort of reset so if you wanted to add more selections. Or is there some other way to have a large list of items that the user could select and then have only those items be displayed?

 May have to be a code solution, I believe the multi selection list box output is always the last item clicked so you have no logic to use to filter future results.
