Filter on draft quality?

Hi,
Would it be possible to add an option to filter on the genome draft quality (high, medium or low in metadata)?

Start by locating the existing filtering entry point and how genome metadata filters are represented. Check whether current options have associated tests or documentation, then define the draft-quality values as high, medium, and low. Done means users can select a draft-quality filter and the selected value is applied to the metadata.
