Filters: No option for blanks

Hi,

The new filters are great but I can’t see an option to pick blanks.

As an example, if I’m using the area filter, I can pick kitchen, I can pick bedroom, basically, I can pick to filter the things that have area assigned. What I’d like to be able to do easily is pick the things that are blank so I can go and correct them.

Or am I missing a trick here?
