What has changed?
When setting up a list field, you can now enter in the list items all in one window. You can separate each list item with a comma or carriage return.
When selecting to add new items to the list, you will see the following window where you can type in the list of items to add or cut and paste the list of items from another source such as Excel. The Add Note Types window looks and works the same as the Add List Items window.
Copying a list is as easy as copying the data you want to make a part of the list and then pasting it in the Add List Items window.
When you then Add those items, the values are parsed into a list of items.
