Files & Folders report tweak help request

So i am scanning our desktops for any listing of java.exe and dumping that to a collection which works fine.  I then built a simple report to output the filename, desktop name, path, and product name which also works.   The issue i have right now is if i have say 300 desktops that all have the same product, for that particular file/path the report shows it 300 seperate times.  wondering how i can tweak the report to ONLY show 1 instance of each path if that makes sense since i'm mostly interested in gathering how many unique paths that we have java.exe .
