Centering part of the text, within a text bos?

I'm struggling with what seems like it should be an easy feature. What I'd like to do is, within a single text box, have both left-justified and centered text (this is part of a credits roll).

Attached is a very poor diagram of what I'd like to do. It's very easy to left, center, or right-justify the entire text box in the Essentials Graphics panel, of course, but that's not what I want. Copying & pasting from a different app makes no difference, as the formatting is dropped/ignored.

Is there a way to do this? Mucking around with spaces wasn't a great time!

(This is using Premiere 23.4.0 on Windows 10)
