If I have a few concentric circles I can select all of them and modify the location of their centers using the editor. When I try this with a group of items (example: making my concentric circles into a group) and then try to modify the geometry all I get in the editor window are the attributes of the group. What is the best way to re-position groups of objects? I realize I can use the "translate" tool; however, I would like to be able to specify an origin by typing in coordinates. In addition, if I use the "translate" tool for a group of objects I can only move using one of the corners. Is it possible to add a point to this group, say at the center, and have the group move using this point?
