unique buildings for minor factions

[major_payne]

hi

can anyone tell me how i can copy buildings from the major factions and add them to the minor factions?
for example taking one of the 2 unique buildings from britain and adding them to venice.

i really need some help!

[Ministry]

It would be nice to do a simple copy here, or even create a new capital building for the minors. Rome for example, should have a capital....

Not sure how to do this though.
