I understand.
To help you understand why i need(ed) such a feature i can share a screenshot of my game. In this game you play as a little man thats running around on the surface of a book. As you step on words, they have a chance to activate and cause things to happen in the environment. Sort of like a visual novel.
In my case, i couldn't even use individual text boxes easily. I would need to divide my two existing columns into 3 columns of 2000px. That would make adjusting the text if i needed to add a sentence halfway through a paragraph or remove a few words, a total nightmare. This image you see would have to be composed of at least 12 individual text boxes that would need alignment. It's just not practical, especially if i have more than one level.
I got around the text object limitation by writing all of the text in a 3d party program and importing it as a single image then using a Sprite Object.
