Request: Change username / login

I recently sent an email to the helpdesk on this, so more of a feature request than a question.

I signed up for an account for Zoho Projects, then realised I could also have a Zoho Mail email address.

I would not want to use my Zoho Projects username / login, but without creating a new account (I have a project created on my current account so can't see I can do this and remain project creator etc), I can not have a different name.

Feature request: ability to change account username / login.
