If it’s useful, I made this Workflow (I guess it’ll be called a Shortcut in iOS12?) which takes Markdown-formatted text (so requires a purchased Agenda), organizes notes, actions, and completed actions into both TaskPaper format to feed in to OmniFocus and in to an email (so that I can share my notes with other meeting participants).
Perhaps it might help or at least serve as a starting point?
Also mentioning @mkrgrs, as this sounds like it might be helpful regarding your post in the other thread.
Cheers,
