Doctype with SEEN track but not visible on Filters!

Hi alll,
Maybe someone has come with a fix…
As many other Doctypes we set track SEEN so we can track users that have seen the records…

But for this specific case we need to be able to filter the _seen when adding on the Workspace as a Shortcut the Doctype (Foot_News) so if we have 3 records not yet SEEN it will show the number on the Shortcut.

Thanks in advance
