There is not a great way to handle this.. First, I should point out that while you can customize this notification, it really is more of a order-based notification. If only a single catalog item is selected, the custom notification will be sent out. If the order contains multiple items, then the "global" notification will be sent out. About the only way that I can think of to customize the 700+ notifications for general catalog items, would be to insert rows into WD_notifications. If you customize a notification at the catalog item Level, App Broker basically copies the orginal row, and inserts it into this table. It sets the PackageID colum to the package ID for the catalog item where the notificaiton was changed. You'd basically need to insert a new row for each general catalog item, setting the packageID colum for each new row that was added.
