I am trying to override the mass properties of a single part within an assembly. To do so, I select the specific part and click Tools > Evaluate > Mass Properties > Override Mass Properties and input my desired values. However, when I do so, it changes the mass properties of ALL copies of that part in the assembly. 

I performed this action using 3D experience last year; this is the first time it has occurred this year. Has the software changed to make it like this? Please provide any guidance to change the mass properties of only a selected part in an assembly!
