What would be the best way to create a choir score in this way?

I was just working on a score that I thought would look better with the staff labels having center alignment, and I noticed that option is missing from paragraph styles in Dorico 4. Did it get moved somewhere else, or has it simply been temporarily removed? This, to my eye, looks atrocious and I would really like the ampersand to be centered…

EDIT:
I’m an idiot. (sort of) I couldn’t tell that you could scroll down

The default presentation of this window in light mode makes no indication that there is more to the dialogue. It is so faint, the modules fit nicely in the dialogue, and there is no scroll bar, thus I had no idea.
