Post History

I want to write a few canonical questions.  I'll ask these questions, then also write a detailed answer.

On SE there was a feature where you could write an answer to your own question before releasing both onto the site.  In effect, you could post the question and answer simultaneously.

I used this feature a few times for such canonical questions on SE.  Writing a good answer takes time.  I would like to avoid others wasting their time writing answers until they see what I'm going to write, particularly if they see the empty question and also put in some effort to write a canonical answer.

Is there any way to do this here?
