[Inkscape-user] snap, snap to: center, rotation center of groups

Hi Friends, Are we supposed to be able to snap, or snap to, the center or rotation center of groups? I can't seem to make it happen. I can snap to the centers of individual objects in the group, but not the center of the group. I tend to think of a group as a type of object. But maybe not?

Thanks for any clarification :-) brynn
