No, that will also sort the data.

For general purpose application this is sort of meaningless. If an item
appears multiple times in a list, which one do you keep? Once you start
removing items you can no longer preserve the original order.

Of course you might arbitrarily say "well, I want to keep the first
one". If the array is small you can write a procedure that can do this
fairly reasonably, but Panorama does not include that as a built in
feature. If the array is large (more than a couple hundred items) then
it may be difficult to get good performance.
