Name on client portal invite

Hi, An example is that I have a client called Geraldene but she never uses her actual name and is called Dene by everyone. In the client setup I put Geraldine in as her first name and Dene in as the Known As (now Nickname). When I set up portal access the welcome email and portal show the name rather than nickname which looks a bit awkward. Could the system be changed to pull through nickname instead? Thanks, Julian.
