Role groups

It would be very useful if Discord could group functions, as it does with channels grouped into a category. An implementation of this would be the possibility of synchronizing all the permissions of that role group, and also add a permission, so that certain roles only have influence over roles from the same group. For example what would this be used for: I have a group of "Policía" roles on the server, to help maintain order, and I could create a "Internal Affairs" role, to resolve issues of police conduct, and this office would only have some kind of permission over the police only and not over all other members, as is usually the case.
