Scanner > Scan queue > sort by URL.
Need a way to right-click and say "Remove Duplicates".
Items in the scan queue with the same URL might still be very different and warrant separate scanning – e.g. different methods, parameter names or base parameter values. The best place to do the consolidation you’re looking for is when sending items in bulk for scanning. In the active scan wizard, there are various options to remove items with certain features, including duplicated URL and parameters.
