No, hiding until approve/publish per topic or post is currently NOT available either as a feature, nor as a mod.
Until SMF 2.0, it will not be available
Still alot of people have requested it be backported or a mod created for it.
But I personally doubt people will want to waste timing duplicating something that will be a feature in future.
Furthermore in my opinion, it would be a very difficult mod to make, and the no. of active people making mods who are capable of implementing it, is very limited (? less than a dozen)
