Add *before* directives in the new UI
While it's great that the new UI includes directives for us to target when we do customizations, we're generally limited to only putting things AFTER what we may want to manipulate. It would be good to have an easier way to inject our customizations before.
For example, I'd like to place some helper text before our Online Access tab on some items based on the PNX. Right now, I have to put the message below and then do some DOM manipulation. I'd prefer to avoid the DOM manipulation altogether.
