Can I add my Spouse 2 same Web Appointment as mine at a later date.

[Snowfall]

I will be required to get my 7th year Visa Revalidated in India in April-May 2006. Expiring in Feb 2006. I am making a web apointment during those months as I need to travel to India.
If I get married during my trip, can I add my wife as a dependent to the same appointment as mine.
Has anyone been in this boat.

Thanks
Sunil
