Rebranding the login box to allow site-based prompt

Hi
As per the image in Peter's question, https://community.3dsbiovia.com/servlet/servlet.FileDownload?file=00P3800000hn99gEAA
The login page says "Sign in with your BIOVIA Account". This has led to several people questioning whether they are on an internal server and also what username/password to use. Is there a straightforward way to configure the prompt to something like "Welcome to Pipeline Pilot at . Please login with your credentials"?
Thanks
Stephen
