I have a solution that can automate the copying of field groups to options pages, end keeps them up to date if the master field group is altered. It’s been a wile since I’ve worked on it, but I thing I remember building in hooks so that they number of copies and where they are duplicated to can be automated, or at least I was thinking about adding a filter. I’d have to take a look at it.
