Large number of landscape pages within a portrait doc--do I have to textbox by hand every landscape?

Word 2007 on Windows 7

200+ page document. Of which about 1/3 are landscape pages. They're all paginated throughout--no problem with continue from previous section or any of that. But all pages must have numbering consistently on the portrait orientation bottom-center (in other words, I've got a bunch of landscape tables that need a rotated text page number on the left margin).

I know I can manually place a text box in that left margin, use gridlines to center it, turn the text direction and populate the page number. But I so don't want to do that 70+ times! Is there someway to automate this process?



Worst case, I guess I'll copy/paste the text box so I know it goes in the exact same place on each page, but it's still a pain that I'd rather work around.
