Force title break in apa6e

Apologies in advance: this is not minimal in the example but I am afraid my lack of knowledge about what packages control what could lead me to leave out packages that have an effect on the output.

I want to break the title of a document where I desire, not where LaTeX or packages do. My title is currently broken like this:

Research Analysis Exam: A Critique of Evidence in Teacher Education: The Performance As-
sessment for California Teachers (PACT)''

I want to break it like this:

Research Analysis Exam: A Critique of Evidence in Teacher Education:
The Performance Assessment for California Teachers (PACT)''

Though centered of course. How can I do this but allow LaTeX to hyphenate the rest of the article in its usual way?
