there is an NS object biconic Zernike which make use of Standard sag and you could assign it to be gradient lens. this is the closet I am aware of, but since you are looking into phase plate, not sure if Zernike Standard Sag would be much use to you. Some conversion mught be required.....

Thanks for your help and instruction! I'll try to do that follow your guide^^
