Sort by titles without cover art

Is there a way to create a sort for titles without cover art?

The presence of covers can be accessed via the property in %_covers%.
So you may either create a column that shows the number of embedded covers.
Or you may just as well filter for files without covers with
%_covers% MISSING
or those where there is one
%_covers% PRESENT

would that be:
Actions/Create new/
Format value "_FILENAME": %_covers% MISSING ?

No, it is a filter which you enter at the bottom of the MP3tag window. (Press F3 to show and hide the filter input box).
Filters cannot be used in actions.

thanks. I'll try that.
