Add or change one-time password email address manually

Hi Guys,

I am seeking assistance to know if we can change or add one-time password email address manually. I have logged into Forefront Identity Manager 2010 as an admin and try to add or change one-time password for a user but it is greyed out. Is there any option to change OTP email address for a individual or bulk users manually instead of sync with database ?
