Loose Page Output to PDF

[graphicsource]

How do I use Loose Page Output to PDF (Vector output) and keep either a Sheet Mark and/or Page Mark at 100%, when I want the art to reduce to fit an 8.5x11? Everything works great, except the Sheet Mark and/or Page Mark reduces along with the art. I need the mark to stay at 100%. It's a header that should always be the same size. If I choose Fit to Media Size (11x8.5), the art has to reduce by various percentages based on the size of the art. Problem is, the Marks are reducing also.

I attached an example of what I'm talking about. I need the chart at the top to be the full width of the 11x8.5. Instead, it is reducing along with the artwork.
