Workfiles - Ability to filter workfiles by task name based on workfile filename ( or metadata )

At the moment the workfiles app just shows all files it sees in the work dir, no matter what task they got created in. The launcher shows only registered workfiles, but it does provide a cleaner experience if you opted not to use task specific work folders. A feature that resolves the task from a workfile by its name or metadata would be great, so workfiles can filter these properly.
