You can do that via customization scripts. Example:
procedure OnColumnGenerated(Args: TColumnGeneratedArgs);
begin
if Args.DBField.FieldName = 'CreationDate' then
begin
TCodeSnippetExpression(Args.ColumnAttr.Arguments[1].Value).Value := '[TColumnProp.NoUpdate]';
end;
end;
If you want different DTOs (classes) for different endpoints, then in this case you need to effectively create different DTO classes for each endpoint.
