Modify ExifTool metadata?

It is possible to modify exiftool metadata with advanced renamer?

I'm trying to use the PDF embedded dates to replace the file timestamps but it is not working.

I'm using Replace action with:

Replace this: <ExifTool:FileCreateDate>

With this: <ExifTool:CreateDate>

If I open the exiftool I can see it can read the metadata dates for the PDF so there is not the problem. When I click on rename nothing happens.
