Hey @AKlebus , Apologies for not getting round to this sooner. Given that you have moved onto new opportunities are you still willing to finalise this PR or would you be happy for me to adopt it ?

(e.g. do you still have time / interest to make any changes if needed or are you happy for me to just take over?)

Hi @gowerc , thanks for asking. In the near-term I will be quite focused on other projects, so I'm happy for you to take over. If you feel you feel like any input from me is needed, however, I'll make time for it as best I can. All the best!
