How assign anisotropic material based on Solid coordinate system in CST Microwave

Hi
i have trouble with anisotropic material assignment based on Solid coordinate system using CST Microwave Studio.
When i open new material dialog, in General tab there is not any option to change coordinate system. i have done everything but it always show xyz coordinate. how can i overcome this problem. any comment and suggestion with CST Software is welcomed.
Wish all the best.

As it turn out there is a problem with CST MICROWAVE SUITE, it dosnt support this kind of coordinate system for anisotropic materials and the user has to align its structure along xyz axises, its a big bug so,
