any idea when this will be available?

As far as Team Kodi is concerned, this is a dead feature. The original creator suddenly disappeared, which is unbelievable in itself considering the amount of time and effort he devoted to this new feature which was almost complete, and certainly in a usable state.
@Greg25 commented that he would like to continue the work, and has not been heard from since.

I think this is just a doomed feature.
