How to rotate station numbers 180 degrees 2

[PPG9999]

I'm using Civil 3D 2010 and would like to know how to rotate station numbers 180 degree without exploding the alignment. I tried to do it on Edit Alignment Label, but it didn't work. Thanks in advance.

Edit the alignment label style.

I did, but it didn't change. It just moved the station from top to bottom vice versa.

In the alignment label style editor, go to the "General" tab and under "Behavior", make sure "Plan Readable" is set to "False".
