How to Edit Email "From" field for Alias accounts

Hello:

Is there a way to customize the "From" field for emails I send using my Alias Email accounts? Right now, this field's value defaults to the text before the  @ symbol e.g. for the alias email:   myname@email.com the recipient will see 'myname' in their inbox's 'From' field.

Thank you in advance for your assistance.
