Header and Footer Margins...

Question

I don't think anybody has gotten headers and footers 'right' yet. They're painful.
Anyway, I've got a document with a footer: it's got some text and page numbers. I can see in the Inspector>Document that the margins for Headers and Footers are limited to the space from the top of the page (Header) and the space from the bottom of the page (footer).
The width of my document is 8.5" standard. Yet, my body text is sort of in the middle and is 6" wide. My document margin is at 1" from the right, so the text hits the 7.5" mark of the right-side of the page. I'm wondering how to get the footer over to the right past the 7.5" mark to the 8" mark. The reason I want to nudge it half an inch over to the right is that I've got some graphics that push out to the 8" mark. In my document, the widest graphics are still half an inch from either side. Thus, I've got half an inch padding on either side.
Doesn't seem to be anyway to format the margin of a footer/header in terms of the space of the text from the right side of the document.
I know there's 2 things I could do, but wondering about margins here for footers and headers.
Solution 1:
Shrink graphics down to not go past the 7.5" mark.
Solution 2:
Use text boxes for the footers and place exactly where I want. I can make 1 textbox and place it exactly on the page... where I want it. Then, I can copy that, and, paste it onto each page... it'll paste it in the exact spot where it was on the page that I copied it from, thereby negating the need to position each one.

Answer 1

Set your document margins in the Document Inspector to what you want for your header and footer, then set your text margins in the ruler by dragging the blue triangle.
