I suppose we could use a linking thread. It would probably be a pain in the butt to use, but I believe it would fully solve the issue.
For example, I will add a (double) link to a post in the test thread from here without this thread’s title appearing in that post in the test thread.
Here’s a link that will eventually lead to a post by @Pleonast in the test thread.
It does work but it is indeed a big pain in the butt. In the test thread, the backlink shows the title of the interim thread, which is harmlessly titled “Linked from another thread.”
