Description Apple-ID e-mail accounts iPhone

I have added a couple of iCloud accounts in settings/mail/accounts. These accounts are in addition to the one I use to sign in to iCloud on my iPhone. 

In the Mail app, all these accounts show up with their full email address. I want to give them a ‘description' or shortened name to keep in neat. While this option shows up for non-iCloud accounts like Gmail, Outlook, etc., it doesn't show up for iCloud accounts. But on the Mac, I can add a description to all accounts, including iCloud accounts.

Is there a way to accomplish this on the iPhone?
