Add [id://`id`] to your Free Nodelet Settings and (if it's not already) turn it on in Nodelet Settings.
Update: Golly, the mess you can stir up by answering something quickly when half awake in the small hours of the morning! First off I didn't grok the question so I answered what I though it said, not what it actually said. Then I looked at the Node Status nodelet, but decided OP didn't have it available for some reason (note the first problem). Then I remembered I had something like the magic string in my Free Node (for reasons I don't recall) so I cargo culted that into an answer.
monarch's question is good and McDarrens solution looks like a good way of avoiding updating any PM code.
I leave you to ponder what else could be put in back ticks in a string that PM will render as HTML. ;)
