Sure. Use the program as it was designed. It saves the "official title" as Original title, and allows you to set Title to anything you like (e.g., the "English-language title")—if you set not to be overwritten. If you prefer to display Original title in the list, configure it to do so using Preferences-Movies-Titles.
So, for example, when you add "Ichi the Killer," the result should be Title: Ichi the Killer, Original title: Koroshiya 1, and AKA: Ichi the Killer, Ichi - O Assassino, Ichi the killer, Koroshiya ichi.
