I am in the process of putting something like that in place, see:

https://bugs.freebase.com/browse/DA-792

Just by marking your non-unique property as unique, the process should  
find it and add it to the queue for uniquifcation.

One thing to keep in mind is that the uniquifer will attempt to keep  
the most precise, last added, user contributed value.  You would  
manually have to cleanse if you wanted to save specific assertions.
