Modify a Microsoft Word Template

I have a Microsoft Word template that needs to be modified. It is a one page product line sheet that needs to work in the following way: 1. We have a one page template. We need the template to be many pages of eight products each. We are constantly deleting and adding items. Each time we add a new product or delete a product within a page, we need all the other boxes to automatically be reconfigured/sorted to remain in order throughout the pages. For example, let's say we have on page one of the template photos/products E1 through E8. On page two, we have products E9 through E16. If we delete product/photo E7 from the first page, we need E9 to move to the first page and the second page to now have E10-E17. 2. We need the spacing fixed so we can add more text. 3. This must be done in Microsoft Word.
