LIBRARY FILTER: Ability to specify = WITHOUT [Content Tag]

It would be helpful to be able to search through files in the Library by using the Filter and set Content Tag exclusions.
I.e. search for files that don’t have the specified tag/s, or no tags at all.

(1) This would help us manage our file tagging. For example we apply tags when uploading a new file and this would be a way to check if that was done, and done correctly.

(2) Also if we want to apply a tag to all files in a folder, and because there is no ‘Select All’ option (meaning we have to manually select each file), this feature could be used to double check that we have actually assigned a tag to every single file.

(3) I also uses a series of tags to indicate the transcription review and editing process:

• Transcript-Raw

• Transcript-WIP1

• Transcript-WIP2

• Transcript-Complete

It would be beneficial to see what files don’t have these tags, indicating that have slipped through the gap.
