Best way I could think of is shared strings, I mean, it's the only way, really. If he adds sync object, you could put on a synced text object. But it's also hard because of a character limit, AND only one shared string. Here's an idea: (kind of hard, though). If you can sync the object's animation, maybe make it so there is an animation for each letter? (e.g. a, b, c), and then changes through them really fast, adding each animated character to a string. Hard tho.
