The "Create a Sovereign" feature is great.  But in many cases, it will be a trial-and-error basis...people might want to try different combinations of attributes/professions etc. and run them through game scenerios to find out which combination gives them what they want.  Right now, that process seems difficult.  Unless I am missing something, there seems to be no way to take an existing/pre-created sovereign and "tweak" the distribution of attributes slightly - seems like you have to recreate a new one from scratch.  And if you gave a previously created sovereign your "favorite" name, you are stuck - can't delete the old one even to reuse the name on the new improved one.

I think allowing the "reopening" of an existing sovereign with the ability to change attributes, names, etc. and resave would make it much easier for everyone to ultimately create the sovereigns they want.
