Rename part property names in Orcad Capture

I use OrCad CIS for my schematics, but now have a schematic where the property names (not value) does not match the standard names. 

I could create a new DB connectors, but would prefer to rename the properties to my "standard".

To make matters worse, the property I use as key in the CIS lookup is one of the properties I would like to change.

There are 400+ parts in the schematic, so I would prefer a programmatic way.

Example: 

Part Number -> PARTNUMBER

Manufacturer -> MFG
