How do you check the rank of dynasties?

In a game where building Prestige and where dynasties competes in many ways, I would expect an easy way to see how the dynasties rank. I found no such thing, but I might have missed something? Now that I need a full rank of my dynasties, I see no other way than to visit each and every household. Isn't there some easier way? We get the fine list of nobles in the world map, which is a nice tool, so why can't the game alsop provide a list of all dynasties? It knows each dynasty's prestige score, so why not share it in a common list covering all dynasties of a save?

What do I miss? Love this pack, but this detail confuzzles me a bit. Shuld be pretty easy to include, so why did they not?

How do you keep track on what dynasties have the better (and worse) prestige in your game?

And, what effect do a dynasty's prestige actually have, beyond buying perks? When Ermelinda meets Cordelia, will she know whether the Abrantes dynasty's prestige is better or worse than the Thebe dynasty's prestige?
