You have the ability to add items that you have already created to other assignments.
Note: It is important to remember that when you do this action these items are considered shared across any assignment that uses the item. This is convenient if you want to update an item once and have the change reflected everywhere automatically for you. However, if you do not wish to share the item across the assignment then you need to duplicate the item before making any changes to it.
Select Find items to add items that have already been created.
Search for the items you want to add. You can select multiple items by using the checkboxes to the left of the item.
When you have selected the items you want to add, click Add Items under the search bar.
The items will now be added to your items list.
