Center all Text in Middle of Page

I wanted to see if there is a way, in word processing mode, to center all of the text from the middle of the page (i.e. - if you had the word "DOG", it would be centered both vertically and horizontally on the page. In MS Word, you can do this via Page Setup/Layout/Page Vertical Alignment. I can't find a way to do this in Pages. If I import a Word doc that is already formated this way, it stays formatted this way in Pages, but, I just can't find a way to create it this way in Pages. Thanks. Brian
