Is it possible to make songs sortable?

Is it possible in Charts to add a field to a song (where you edit or enter a new song - original composition, etc.) so it is searchable - i.e. find all songs in key of G; or find all Christmas songs

In Charts, you can set a song’s key and tempo, but you can’t add custom searchable fields or tags. Section names and lyrics are searchable, so for themes like “Christmas,” the workaround is to add that keyword into the song title or notes, so it shows up in search.
