hi! we've only enabled this feature in very early beta (only 5 orgs) and we're not sure if we plan to keep it / in what form, so I'd like to hold off on docs if that's ok!

@goeln Oh sure, thanks for letting me know. I wanted to make sure this didn't get missed because it was a Q3 KR, but will note the status.
