Are you able to reorder unit pages?

If so, I am unable to for some reason (using Chrome, if it matters).

I assumed you would be able to drag and drop, much like how you reorder the units themselves. I do notice when I hover my mouse near the page numbers the four headed arrow comes up which leads me to believe the functionality should be there, but I'm unable to actually grab the pages and reorder them.

I've granted support access incase you'd like to go in and take a look.
