Hey @thnkslprpt, would you be able to resolve the conflicts? Thanks!

Tied myself in a few knots and somehow closed this PR.
I know it's possible to re-open this PR, but thought it might be simpler to re-submit as a single commit without the merge conflicts etc.
#370
Apologies for the re-assessment...
