Makeup designer and costume designer

Just like the director, writer, producer, choreographer, and the composer roles, can we add makeup designer and costume designer roles?

To add a crew role (i.e. makeup designer) that is not one of the pre-selected options, first add the role as a Character (with the name "Makeup Designer"), then go to Edit Role, and check the checkbox for "This is a crew role." That will make the role appear the same way the other crew roles do on the site.
