Triumph question

Currently Roman generals can get triumphs for defeating the Gauls, Carthaginians, Germans, Britons, Macedonians, Syrians and Dacians. Is it possible to add traits to allow triumphs over other factions like Epirus, KH, Lusotanna, and Egypt? I can cut and paste from what is already there but I would rather not make the huge effort if there is some kind of hardcoded limit on traits or something else that will prevent it. Thanks!

I've got Triumphs out of Luso's and Greeks before...

Hmmm, yes... I guess what I really wanted was specific "Vanquisher of blah blah blah" traits. Which I guess is indeed separate from the triumphator traits. Sorry.
