Question on adding buildings

hey guys, I was playing as the Senate the other night and I noticed that they don't have any religious buildings. this could prove to be a problem when taking far off provinces from the capital, especially since these provinces will be of a different culture. How would I go about adding in some of the Roman temples for the Senate?

You have to mod the export_descr_buildings.txt file in order to add the senate to the temples that you like. Notice that the temples are categorized by their abilities, for example temple of leadership etc.
