@bbakerman - Any idea when this PR can be looked into ?

This would be great to have.

Bump.

Wanting to make sure I'm helping to show there is public interest in getting this merged in.
Thank you @ravikancherla for coding it up - I am currently using it.

This PR has been open for a year, if there's any of requirements for getting this approved that I can help with I'd be open to working to get it to meet them if @ravikancherla has disappeared/lost interest and the admins want help to move this along.

@plaurina - as far as I know I have passed all the checks and have been waiting for admins to merge this PR for over an year 😊

Of course with conflicts because of new changes happened after that. Feel free to resolve the conflicts. I think that’s all is needed from our side and admins have to merge this PR after that
