Is this a unique feature?

Is your feature request related to a problem/unavailable functionality? Please describe.

Proposed Solution

Should be available through extend:

Headings.HeadingThree.extend({
    renders: {
      "heading-three": ({ element, attributes, blockId, block }) => {
        return <Typograph as="h3" {...attributes}>{children}</Typograph>
      }
    }
  })
