Creative Work schema

Great plugin, it has helped alot to get us organized with out schema structure.

I know there are quite a few schema types that your plugin provides, actually the most of any other plugin, but is it possible or how do I add more specific types of schemas for Creative Work.

Like we need to add Painting, Photograph, Poster, Publication Issue, Publication Volume, Drawing and Visual Artwork. Or adding specific properties like copyrightYear, issueNumber, copyrightHolder, funder, publication and publisher.

I know I can adjust/ modify the schema output and add a property but there isn’t an option to add custom properties. Maybe that can be an added feature? Also I see we can add custom schema but that seems to be for individual posts.

Thanks
