Ustraveldocs profile

Hello, My husband and I hold separate H1B visas. We have different approvals and created separate DS-160 applications. We both qualify for dropbox appointments.
For appointment scheduling, I used my usvisatravel docs account to schedule appointments for both os us together. It shows both our names, visa class as H1B for both, but one of the columns (is Dependent shows as True). Does each H1B holder need their own ustraveldocs profie? Can we appear for the interview this way?
