Conditional Shipping and Payments

If I set up a restriction, either globally or for a specific item, there should be an option to automatically append information about that restriction to the the description of all affected products. For instance, I have a product that can’t be shipped, and I have the custom notice set to “{product} is not available for shipping.” I should have the option of having that text appear in bold below the item’s description, without my having to manually type it there. I also have a shipping class of items that I won’t ship. There should be a similar option to include text to that effect on all items within that shipping class. This seems like it would be simple enough to implement.
