Update 15th September 2021
Thanks for your continued patience with this request and for everyone who provided examples and reached out for early access.
The feature is still in development and we're working on enhancing the solution to cater to different cases as we've encountered from the examples. We are also blocked on a few internal dependencies. All this means that our delivery date is pushed out to the Oct - Dec quarter to ship an experience that works for most types of content.
This is a difficult situation for us as we are trying hard to ensure that this is no longer an issue for our customers.
