@songy23 thanks for filing this issue! Please assign it to me or let me know when you are stepping through it and I can write the handler to do this.

Thanks @odeke-em! Assigned this issue to you

[songy23]

Apologies, looks like I cannot assign you because you don't have write access to this repo. @jparsana can you help here?

[jparsana]

@songy23 neither do I. @bogdandrutu @shahprit can you help here?

@songy23 @rghetia PTAL I've submitted #115

My apologies for the delay, I've been OOO and travelling abroad so didn't get a chunk of time to work on it but I finally got some and submitted the PR above.
