Hello Troy,
Sorry, you are not able to have the aliases as the From address. Aliases are primarily used to be configured for individuals to send to those addresses which have an email address associated to them. You are not able to log in with aliases or manage the settings. I would suggest you can create an alias name such as 'sales, info, or support' and then have individuals send to that address. You may want to include that in your online publication or materials so that the mailbox actually gets sent the messages and the alias is used.
Thank You.
