Updating a sale without bumping.

I am trying to change the details in the first post of a thread in the advertising forum. "Edit Sale" will only allow me to edit the lead in information, not the advertised details. Hitting "edit" in the post gives me a "bump post" dialogue which is not what I want to do (and not possible either, because it is less than 1 month old).

So how do I edit the text of a sale?
