Okay I have an idea, it is possible (with a plugin) to add an anchor as soon as some one adds a first reply?

So when replying, it checks first if there is 1 post in the topic. If it is, it adds a anchor (or get its anchor) if it isnt (there are 0 or >2 more posts) it does nothing. Then it can generate a first-reply link…

Well in theory…
