Can you unblock a tutor?

I’ve accidentally blocked a tutor (tutor). Basically, I wanted to not be randomly allocated the tutor, but I didn’t want to block them forever. And now I don’t know how to unblock them.

It would be nice to have a blocked tutor “stay” in the “Your Tutors” section, but greyed out potentially, this way I could block and unblock to my hearts content.
