This is accurate. We do not support it at this time the way we have and are still considering it as a potential candidate to be added in the future. It’s not been x’d off the list yet, it’s also not trivial to implement. Hopefully we can do this sooner than later!
Can you tell me more about your app and how you’d want to use this feature? What does it add to have or take away by not having?
I can take this info back to the team when we meet next! 
no promises but the more info on a topic the better to help us understand how to prioritize things.
