Hello!! I just drew them in on the first tread and selected them both to the same group ( the posts). Then with them un-selected in the model, I used the cursor to select - click on the word group in the Outliner. This is what /how I highlighted them and produces the “sliding selection bar” (???) for lack of better term. Moving the curser while selected moves it and were you stop determines the exact placement of the group in the model.
