Yeah having them on the map would be interesting, though it could be an issue having potentially up to 48 different prophecies displayed on it. 
I did suggest having a CoF Faction Window Sort & Search in my previous version of this system rework, and I did link to it at the end of this one as something I’d still like to see.
That said, Mike (an EHG dev) did respond with the following when such a suggestion was made on Reddit:
Sorry but neither of those requests will make sense after the rework.
So clearly the upcoming CoF rework in Season 5 is going to change a lot, or at least enough about the system that it makes such a change not needed.
