autostamp a section of the filename onto header of multiple PDF files

We save a lot of PDF files one a daily basis and we need to stamp on top of each document a section of the filename.

The sample filename would be - 023 - PID 123456789 - ABC 1234567

The PID and 9digit number after it will always be different, and needs to be stamped on each document. Is there a way for us to batch stamp each document and is there a code to section off just that part of the filename for maybe, a dynamic stamp. We only have Acrobat Reader DC.
