AutoCAD Inventor :: Save Copy As For IPart And IAssemblies

It has to do with iparts and iassemblies and “save copy as”.  My concern is that during the concept stage an engineer may be working on a design and will create an ipart, as many of our designs have multiple versions.  They now want to keep a copy of that ipart, and try something new so they “save copy as” and create a new file.  The new ipart members all have the name reference to the first design.  Does renaming those members redirect the path to the new ipart, or should we avoid designing like this all together?
