Change of Administrator's user name

Dear Zoho Projects Team,

I created a company on Zoho projects with my personal eMail address to test the application (among others) before choosing one for my company.

Currently I am Zoho Projects' Administrator for my company using my personal eMail address and I have also a Manager account with my business eMail address.

Is it possible to change the user name for the Administrator Account? I would really like to use my business eMail address in this regard.
