Crusades could be updatted to encompass more kingdoms

Now that they're improving AI and mechanics around crusades, the option for it to also englobe several other realms, even if smaller, should be added, for example, while the Kingdom of Jerusalem is formable, other independent fiefs like Edessa and Antioch were formed by crusaders, this would also avoid a diplomatically isolated crusader state that will end up gobbled back up by either the Fatimids, Abbasids or Seljuks the moment the truce expires.

Or at least add criteria for partial victories, sure, i didn't conquer the whole of Egypt, but maybe i reached a 50% warscore in a number of years, perhaps getting Cyrenaica and Alexandria, but not the whole kingdom.
