Filter on Graded Condition (Not Specific Grade)

For Categories where you can specify grading details, there is no current way to filter your collection to show all graded items regardless of their specific grade under the “Condition” filter. Current options are either “Ungraded” or selecting a specific grade.

Would be useful to also have a “Graded” filter option under the “Condition” filter in order to just see all graded items regardless of their grade.
