I saw this thread come up and wanted to jump in with an update on this feature request. Cody was accurate that the initial development had started and was previously slated for a May / June time frame.
About six weeks ago, I had the difficult task of assessing and prioritizing features that are being worked on and am sorry to report back that we have stopped development of this feature request for the immediate future.
I understand this is probably not the answer you wanted to hear and thus would welcome the opportunity to take the conversation into a private thread if you'd like like to discuss further. I can be reached directly via email: firstname.lastname@example.org.
Thanks for your understanding in this matter.
