A list of multiple Tags can be imported from the company settings under Tags.  The list must be contained in an excel file with each tag listed on a new line in a single column, as shown below.

Click Import and browse to select your excel file.  The system will check the file is valid and display a message to help you correct any issues.  Once the file has been validated, click Import.

Once saved, you are able to edit or archive any of the tags should you wish.  

Note that when a tag is archived, it will no longer be available to apply but will still be visible on items it has already been applied to.
