Marshman, I think I'm having the same basic scheduling issue that you are. I have not figured out how to move a "group" or "route". I have to move individual visits for an entire day if it rains or other scheduling issues arise. I only have a few customers now, but it would be ugly if I had a full schedule. I'm not sure that I want everything to just "slide" a day if it rains, but maybe I do....
