Oh no you misunderstood what i asked. I have been searching for many maps, historical facts of each city and province trying to make a progression of the roman territory. Discovered this site which has an interactive map and timeline of most empires around the world:

And was just attempting to reproduce actual history in rome 2 tw. Though it was frustrating how every time an important nation lost against a nation that shouldnt exist anymore according to the records. Think of it as a "History Mode"... With a certain Carthaginian army going all the way around france and crossing the alps and so on. But the current AI won't do that. I know it would destroy the sandbox-ish part of the game but its just for that end really.
I do believe this im asking is not possible or its uselessly hard. Would you think about bringing back diplomacy on territories? Plenty of times in history cities and provinces were taken not by force. One example of that is how Rome took Corcica and Sardinia, they made Carthage give them to Rome. I feel weird every time i have to take them with an army though... but oh well.
