Finding Duplicates in DMU

Hi! I am trying to find a way in CATIA to highlight any duplicated parts in our DMU. We have some pesky duplicated fasteners/zipties/small components that are very hard to spot - especially in context of 10,000 other parts. Any tips and tricks for how to hunt them down? - ideally something faster than clearance/contact/clash - I'm hoping for a BI Essentials tool or something of the sort
