How could I change the plane type dots to filled color in allegro?

Hi all!

After I change the version of OrCAD 16.3 to 16.5, it is different the type of plane.

When I used the ver.16.3, it has filled color of plane. So I could see which is what trace.

But Ver16.5 has a dots type of plane, it makes me very confused and unconfortable recognising among the nets.

Is there any patch file for changing the defaut type of plane except dots??

Thanks.
