Attribute Management of the existing files without exporting or importing files

Hello!

I would like to know if ProjectWise Bentley Export /Import to Excel tool that comes with the ProjectWise Installation will be capable of exporting a list of file attributes ( attributes are environmental variable values that are exchanged through tag set with ProjectWise) (without files themselves) and to be able to import modified these values and send  back to ProjectWise to update the existing files. I tried to do that on sample set, just by deselecting files to be exported, and it seems not to do the trick.

Thank you!
