Thanks for the clarification.
You’re almost over my head! But I think I’ve pretty much understood - In summary, you may well be able to improve the current cross-doc actions to combine a group of actions. But editing of a cell in a sync table that is pulled from a master version (or view in your pack’s case) will not be possible until (if 
) Coda implements this functionality.
While you’re here, and maybe best to actually respond in your post, how long until your formula guide is released?
