[Help] Changing citizen Focus for puppetted cities

[DocVertigo]

Does anyone have any idea where the data for puppetted cities sits? Ideally I'd like to be able to make a puppet's citizen Focus changeable in-game, but I'd happily settle for modifying the standard puppet Focus from Gold to Default.

Would also be super appreciative if anyone could point me in the direction of how to fiddle with puppets' build priorities (another ideal scenario would be if it's possible to make resource-intensive City Improvements buildable if the player has at least X number of the required resource).

Thanks in advance!
