You can cut and paste the list in by clicking “editor” in the bottom left hand corner of the setup values screen. If you have a long listing of selection items, the editor box allows you to make changes to the values you have entered so far.
The editor can also be used to copy and paste long listings of values. In the Editor each label and value must be separated by a “~” and no spaces between. The item to the left of the “~” is the Label and the item to the right is the Value.
