Api 650 tank

[Engr ZANIA]

Hello!
Im using AMETank to design steel storage tank and i have to use ss400 plates. I know its equivalent to A36 but ss400 is not among the default material list of AmEtank. Is there any way to add ss400 in ametank data base.
Do i need to go for any kind of check for switching A36 to ss400

See 4.2.6 and Table 4.2 in API-650. Does the program allow "Grade 235" or "National Standard Grade 235" or something like that?
