Aliases under the email account

[Former user]

I like to have unique email addresses for all my online logins. So aliases have worked well for me. I have 1 main account and several "sub emails" (aliases) under that account. For example, if i have [e-mail] and [e-mail], [e-mail], etc.. it would be great if the email account screen showed accounts and then i could open [e-mail] and see all the aliases routed only to that account. (they could be called single or associated aliases). It would make the email accounts page cleaner, at least for me. Can something like this be done?
