Good question, but I don't think so.
As far as I know, the only option is to subscribe to a thread, but I don't think that does exactly what you want. Subscribing to a thread lets you know when new posts are added to it.
I think what you would need to do would be to save bookmarks to the thread in your browser. You could sort them into their own TFL-specific folder.
