Mass updating part file attributes

Hi -

Currently we have an attribute in the NX part file called:

DESCRIPT 

We need 2 Attributes added to the part file called:

KB_DESCRIPTION_EN

KB_DESCRIPTION_NATIVE

The value for these 2 new attributes ideally would be copied from the existing DESCRIPT value (if there) or if not , then any value be placed into it (like a – for example), but the 2 new attributes need a value.

Looking for a way to have these 2 new attributes and values placed in during a batch update (or anyway to get around from opening every file).

I did spot check some of the data and noticed that not all files have the DESCRIPT in it, so to be safe I would suppose the second option would be the safest bet to give a generic value that would be updated later.

anyone have any suggestions on this approach?

Thanks!!
