Toolbox, new version just uploaded, will let you half do what you want but the offset air units do not move in patterns relative to the group centre, they are just offset and can be set at their own altitudes. As said there isn't anything I know that lets you set the type of active formation you're after. In many ways you get a better result by splitting the units off into their own groups and seeing where they are relative to your 'main' group and managing them that way.
