Can council of nobles missions be tailored to specific factions, or are they all part of a pool that every faction uses?

I ask this question because editing the text for missions could be an easy way to give the game a Warhammer atmosphere. For example, a potential mission for the Empire could be:

"Terrible news, mein Emperor! A cousin to the count Elector of Middeland has been ambushed and captured while patroling the highway to Skavenblight. The Elector demands that an army set forth immediantly and free his blood relative before it is too late.

This could then be modified for the Dwarves, for example:

"Thunderblast! A travesty so profound I can hardly dare to believe it has occured, O' King. Twenty barrels of Bugman's Brew, fresh from the brewery itself no less, have been forcibly taken while en route to quench the thirst of our miners. Our tavern spies have warned us that they were taken to Skavenblight. The drinkers of the kingdom will toast your name aloud if this wrong were to be addressed immediantly."

Obviously this would not work if all Kingdoms use the same mission statements. I think this would be a great way to add cheesy Warhammer based fluff to the game, and can be started straight away.
