Firstly, apologies if updates seem sparse. We make every attempt to be as responsive / up to date as possible on our JAC tickets, but sometimes, the volume of comments make responding to every ticket impossible.
With so many different features, capabilities, and enhancements we can make to the product, I hope you can understand it's a balancing act for us. I can assure you that, this request continues to be on our radar amongst other priorities.
Once we've made significant progress, I shall be updating this ticket again.
Thank you for your patience and support.

We are aware that this is important and something our customers expect. The good news is that this is one of our priorities right now and we're exploring ways to make it available. While I’d like to give you a clear timeframe for when we can deliver this I, unfortunately can't do that quite yet.
We’ll keep you posted as we progress. Thanks again for your patience.
