Thread:Extension talk:SubPageList/How to list subpages randomly?

I currently use this extension to list subpages according to last edited or alphabetically. However, I currently have the need to show different subpage to appear randomly so the same list of pages will not be showing up all the time. Is there a way to have subpages to be listed randomly with no order whatsoever? I have tried not putting any "sortby" parameter but the default setting kicks in.

Thank you
