- Select the segment
- Move the segment slots to the right
- The new elements appear at the end. Validation errors may be presented as a result of the now blank additional elements if they must have values present.
- After filling in appropriate values to the new elements, the validation failures will disappear. The file can now be saved to persist the additional elements or components.
