AutoCAD Inventor :: Macro Resets Displayed Names In The Browser

We have the following problem (on AIS2010): we often recycle existing designs with small changes/adapting, means: the (sub)assembly is saved with a new name and part number, and the subcomponents that need to be changed, get a new part number and file name too. So we save a copy, save the parts need changes and then replace the "old" parts in the new assy.

Doing so unfortunately retains the "name" of the component in the model browser tree. Why is that in the first place.

But I'm trying to write a macro that resets the dspalyed names in the browser.

What I found so far, is that under BrowserNodeDefinition, there's a Label property which contains the displayed name, and this does not get changed when the part is replaced. So I thought, I can just compare these BrowserNodeDefinition.Labels with the actual file names and forge a new Label from the new name and the sequence number, however, the BrowserNodeDefinition object is read only, can't be changed.

I haven't found anything else that would contain this name that is displayed in the browser.
