Multiples of the same file detection!!!

So, I have given Rekorbox 7 ago. Which is pretty big since i still run 5 till now. It has some pretty fancy features. Mix in mix out points, auto hot cue load and numerous other fancy stuff I haven't even looked at. Why can't they have a tool for multiples of the same track? Find all the file name and then offer to delete the file. Save space on collection lists and hard drive. Or is there that feature and I don't know how to use it?
