From the what i've seen and looked for so far, no. The only way would be if you were a bureaucrat to promote those users only so they would fit into a group. And then limit edits to that group. But then, remember that promoting multiple users at once is not a good thing. As the Wiki might see it as abusing your powers. If you do choose to promote those users make sure they are trusted users that won't mess up the Wiki.
