EXAMPLE:

You might wish to assign a tag to a tag that already exists. For example, if you decided to add the tag 'Clothing' to all items that are tagged 'Jeans'.

To do this you would do the following:

1. From the Tags section, find the tag 'Clothing' and click 'Edit'
2. If the tag 'Clothing' doesn't exist, you can add it now, using the 'Add Tag' button in the top right.
3. Turn 'Show What's Tagged' to 'Off' 
4. In the Tags Search, search for Jeans.
5. Now add the Tag 'Clothing' to all items in the list. This is done in the Tag column.
   
   

PRO TIP: 

You can apply tags in bulk by checking the items that you wish to tag and using the Bulk Actions tool.
