I have a contact layout with a portal listing all orders ever placed by the contact. There are thousands of contacts making a few orders each. But there are a couple of contacts that have a long history resulting in many orders. For them loading the contact page is slow over a remote connection. How could I make it so that the portal shows 10 (or whatever prescribed number) orders at a time, starting with the most recent, and then lets me page through them 10 at a time?
