Control of Cracking Damage via subroutines

Hi, is there a way to change the orientation or deactivate a crack in an element when using Damage -> Cracking option. I have looked at UCRACK and TENSOF subroutines, but I couldn't find crack normal or crack flag options.

Related question, is there a fully customizable damage subroutine, where I can define reduction of the elastic moduli (tension/compression) AND define stresses in the element?

Thank you

Crack is always perpendicular to the direction of the maximum principal stress and cannot change. You may set different ultimate cracking stress, softening modulus and crushing strain for different element to control crack initiation and development using UCRACK.

Thank you for your answer. Is it possible to deactivate (heal) such cracks from any subroutine? I am looking to have more control over this damage model.

Also, is there a subroutine for general damage/constitutive material modeling?
