Set up "sending from" warning on MS Outlook 2013

Question

I have multiple email accounts linked to Outlook:

1. Gmail personal
2. Business XXX
3. Business YYY

Currently, default From option is my Gmail account. Sometimes I will need to send emails from different accounts. When I click on Send button, is there a way to set up a pop-up warning box to say that I am sending from chosen email account.

Essentially, I want to avoid sending email from Business XXX or Gmail to a colleague at Business YYY.
