Changing H1-B Petitioner details on CGI portal after scheduling an appointment for dropbox

Hi all,

Is there a way I can change the H1-b petitioner details on CGI portal after scheduling an appointment for dropbox?
After reading a few posts it seems for in-person appointments you can simply ask the officials to change it when you go to the embassy for the fingerprint appointment. But I am not sure how to handle this for the dropbox appointment.

Appreciate any information you can share on this!
