I'm trying, created a group, drug my obj's over to it, and ran group - capture nodes, but it doesn't appear to have done anything. I don't think it can be done, but I'm new to TG2, maybe it can be?
edit - taking another look, maybe it did group them. Unfortunately, under group settings, there are no transform options, which is what I was really looking for. Maybe a better question would be "Is it possible to group/link/parent objects so that they will all inherit the transform properties of a master object/group?"
