Sort of, but that’s mixing apples and oranges a bit. 
The CSS customization is based on the primary group specified for the user, which may or may not be the title they chose to use on their profile. (You see that in your example above even … the group is “team” but the titles “co-founder” unfortunately get the same styling.)
I’m not sure if that’s a problem or not for OP, but it is for us (trying to do something similar).
