I need to re-order my posts. When I select "re-order" (under posts) it instructs me to select "custom ordering" to drag and drop. Yes. That's what I want. But there is no button or text or other indication or option for selecting "Custom Ordering" I'm unable to load a screen shot, but how can I select custom ordering other than removing all psots and re-creating them in the order I want them.

Thank you
