Bi-directional usage

When Bi-directional is selected, two Set Default Value as Masked Field check boxes are added beneath each side. The default behavior of the Use Default Value field on the left side is the same as the original single one.

When you select Set Default Value as Masked Field, its respective default text field is set as a masked field. This displays in blue.

When you clear Set Default Value as Masked Field, its respective default text field is set as a plain field. This displays in the original color.
