"No Tag" tag list

I am trying to find a way to show a list of fonts that have no tag. I am (trying to) systematically go through my files and tag them to make finding styles and attributes more easily.

Does anyone know of a way to do this such that when looking at the Library in Predefined view, I could select a font, assign it a tag, and have it not show in the list (No Tag) of fonts?

When you have the Untagged Fonts view selected, you can provide tags for those fonts. They will remain in this View as long as you don’t switch to another view or select Refresh. You can see what fonts have already been Tagged, by looking at the Tags column. You can move it to another position in the view, it that is more convenient.
