There is no automatic way to do this that I know of using the Elements Organizer, if that's what you're asking.
I use a separate utility, DupeFile Finder, that works very well for such operations. It has never failed me yet. Cannot recall if it was freeware, or shareware, but if I paid, it was not much, and it has worked fine for me.
For Still Images, I often use the commercial ThumbsPlus, and sort by Similarity. I have version 8, and it did not do X-folder comparisons (like DupeFile Finder does), so one would need those Stills in the same folder to determine dupes. Do not know if the new version has improved on that?
