Add Content to library folders but tag some so Wisdom doesn't use it

Because we don't have library subfolders just yet... hoping that it would be simple and fast to add a checkbox to individual content stored in a folder that belongs in that folder... BUT those with a checkmark would have no business being examined and used by Wisdom AI. Why? Because when the management team here has everything in a folder for a Hub (internal use) all content belongs together.... BUT there is a need to exclude specific content in that library folder from Wisdom AI pulling everything in that folder. Subfolders or additional folders just make organizational taxonomy -- much more difficult. GREAT info for internal Hub use doesn't mean it's great for Wisdom AI use... but it really does belong together.
