Can I easily replace a character in Storyline?

Hi all, 

I have a project, I would like to reuse for a new project. In the new project I'd like to have a different character than in the project I reuse. Instead of Lily, I'd like to use Alex, but with the same expressions, poses, states etc., like Lily in the former project. 

Is there an easy way to replace Lily by Alex in one work process or do I have to do that slide by slide and layer by layer? 

And if I have to do it manually (with right click on the character and then "change character"), why doesn't the name change from Lily to Alex (see attached screenshot)? 

Thx in advance for your help and best regards
Roland
