Is there a way for those of us who own all three parts of Sins to convert it to Trinity for the purpose of easy installing and the like? No offense, but Impulse's game download/installation process is rather painful (since it does everything in one step, so I need to avoid playing games while downloading/installing), and one package when I get in the mood is better than three.

So is there a way to trade Sins, Entrenchment, and Diplomacy for Trinity for the purpose of making it a single download/install? Or am I an idiot and Trinity is actually still the three separate packages for the purpose of installing/playing?

Thanks.
