I don't know any easy way around it.
The problem is when you select the plan - all layers including the 3D model and 2D annotation - you are not selecting the annotation in the sections and elevations.
Not even when you select the section and elevation lines themselves.
You still have to go into each section/elevation, turn off the 3D model layers leaving just the 2D annotation, select that and flip it.
If you ever do find a better way please let me know.
