Due to my limited knowledge of Golang and the way in which this codebase is structured/tested, I'd be happy to hand this PR over in this state to a maintainer to complete and release the work.

The only elements I was unsure about is test coverage (if required) and if the Schema version needs to be updated due to this additional field.
