Have you tried this yet? This is the Insert>Hyperlink method


I made a sample of what you're talking about but don't know how to attach it as I have seen others here do. First slide has 4 links to 4 other slides that correspond to the quarter. Each of the quarter slides also has a "back" link that returns you to slide 1 with the 4 links. You could also cut the first slide (like the table of contents index) out of the equation and just have the links in a bar across the top of each slide(like a navigation bar) so you can click and link to any slide from any slide.
