What I did was create a 3 row table the full height of the page with no margins top or bottom. Keep the left and right margins set to normal. Only apply gray table lines to the bottom of the top row and the top of the bottom row. Take a snippet shot of the entire page. save that as a picture. open the document you want to see the third page lines in and got to the design tab - select watermark - custom watermark - choose "picture watermark" - scale = 100% uncheck "washout". If you don't want to see after printing, remove watermark before printing.
