h1b stamping appointment in Vancouver

[online_friend4u]

My wife and I are planning to go for our h1b stamping in Vancouver, we both opened an account on usvisa-info and paid the MRV fees. Now while trying to book the appointment date

I saw there was an option to add family member, so I tried to add her but it doesn’t let me. Any ideas? Do I need to delete her account? I don’t see option for that though.

The only reason I want to do this, is there are only single slots open for the dates I'm booking and it's really hard to get the same day for both of us.

Any help/advise on how to proceed on this would be appreciated.
