Word VBA - Automatically insert "watermark in middle of all pages both odd and even and different sections fo the same file.

Word VBA - Automatically insert "watermark in middle of all pages both odd and even and different sections fo the same file.

I know how to insert a watermark and automate it.  but I cannot automatically insert the watermark across all pages when there are different headers/footers (odd/even) and different sections within the same file.

I cannot change to document structure either except for the watermark due to standards for the document.

I will give 300 points instead of 100 points for answer that works well for the above.
