John, When you setup the auto label for the wall, go to the Text Label panel and change the to 180º
Alternatively change one of the labels to the opposite side then Opt/click to change the default. Next time you apply the label it will match the manually changed one.
Once placed just select and change in the forementioned Text Label panel
Unfortunately you dont seem to be able to change the lengths of the lines except manually.
Cheers John
