@aviadhahami Is there a chance to get this merged?

[aviadhahami]

@jgrumboe did u happen to test it? would appreciate that (and the addition of tests)

[bcluyse]

Any progress on this would be greatly appreciated.
If possible, I am also up for finalizing this.

@bcluyse - hey! this still awaits @itavy's resolving (which I'm unable to push as this pr coming from a fork)
If you'd like to add the change ( + tests preferably) then I'd be happy to merge
