Can I cancel family member (H4 visa) appointment and just keep H1b dropbox appointment

Hi, I am on my H1B and we booked an H1B+H4 combined dropbox slot same time appointment for me and my wife next month. At the last minute, my wife could not make it to INDIA now. Can I cancel my wife’s H4 appointment from her account without jeopardizing my H1B dropbox appointment? Will it cancel both appointments OR just her appointment when we are canceling through her account? I am a little tense as I really want to make it to INDIA next week. Can you please advise? Thank you!

If you booked separately then no issues.
