From what I could tell, not without creating an account. And because this is something relatively unusual (not as simple as changing a business's opening hours or something like that), I'm not even sure I'd be able to figure out how to do it in a reasonable amount of time. I'm not willing to put in the effort to do all that before I've ever gotten value from the app (since this was a problem I noticed the first time I ever tried actually navigating anywhere).
