Thanks for the suggestion!  I'll definitely add coverage of the other instances in this package, but I don't see an obvious place to put a utility method.  Any suggestions?

New method added, PR renamed.

OCA process is progressing, once finalized I'll rerun checks and publish the PR.

OCA completed, ready for review.
