Hey @Chrissy_Eckman!
It is great to hear from you after a bit of a hiatus — hope all is well!
I completely hear you on the granular permissions. Trust me, you are far from alone in wanting this feature like… yesterday 
Jason from our product team shared a note in the forum a little while back to shed some light on where it sits on the roadmap and the reasoning behind why this very popular request has been a work in progress. If I had a magic wand to make anything happen, this would be right at the top of the list. I am hoping an update is not too far off, and I will be shouting it from the rooftops the moment there is good news to share.
