Thanks for this PR @dkhutch! Unfortunately our CI doesn't run from forks (security) so I've cherry-picked your change into a branch in this repo and opened a new PR with the same change here: #74

Next time we can give you write access so you can submit your PR from a branch on this repo - just open an issue if you have any other proposed changes.

I'll close this PR now and move over to #74

Thanks Dougie. Ok, next time I'll see if I can do it without making a fork. I might need to ask some follow-up basic questions though, because I'm not very familiar with github pull requests.

All good. And to be clear, the approach you took of making a fork is the most common way. We're just a bit cautious because our CI submits things to Gadi.
