How can I change the default username that appears on the typewriter tool?

Sorry it is no way to do that with current version, we have already noted it as suggestion to our PM team for future reference, suggestion id: JR25
Hope it can be implemented in future update soon.

I have Foxit Phantom and use the Typewriter tool to add text to a PDF. Once I have added text, and then hover the pointer over it. it shows my username as cwalter. How can I change this to read Crystal by default instead of cwalter?
