2 Visa appointments

Hi All,

Currently I am on H1B and planning appear for Drop Box appointment for H4 visa considering the current visa appointment timelines.
But I noticed visa appointments are available in another consulates (other than Chennai).

Can I have 2 CGI accounts and schedule 2 different visa appointments (1 for h4 dropbox and another for h1b), is this possible ?
If i transfer my CGI account to new email ID, will the old one will be deleted ?

Please advise .

Thanks.
