Multiple Email Addresses - Different Functions

As a user wearing multiple hats, I have the need to reach out to customers and professional consultants for different purposes and by using different alias email addresses covering various functions. Most times it would be my regular email address, but other times I need to send a general email from HR or Accounting, etc.

I’d like to have the ability to set up multiple emails and choose which email I want to send correspondence from through a drop-down menu.
