You can implement this same behavior using more advanced features like the Update or copy field values or Format field value post functions.

Select the field where the substring should be replaced.

Select the field to copy the replacement value from.

Enter plain text representing a valid regular expression and optionally use field codes to insert field values. The expression will be used to match the substring in the selected target field.
