I set up a handbook for all of my clients, it would be great if I can set up all custom fields for the information and then use placeholders on a custom page so everyone can have their handbook, with their own specific information in it without making dozens of custom pages to accommodate it. It would work for many other scenarios as well, like if someone had a subscription for services that was leveled. The information for the specific level could be available through custom fields and then called/displayed on a custom page.
