We would like to be able to make the tag field a requirement for agents before they can close a ticket. 

This would help with monthly reporting, where a lot of tickets end up with no tag, causing manual work to go back and add the correct tag for each ticket.

Additionally, is it possible to limit agents from creating new tags? An issue we tend to see is new tags being created with misspelt wording for tags that already exist. 

Having the option to make tags a required field for each ticket and limiting agents from creating new tags would be great. 

I already tried implementing this within the Layouts and Fields settings, but couldn't see the option to make "tags" a requirement.
