Replying from multiple emails accounts

I have two email accounts coming into Gmail...and then Gmail is configured on my iPhone 5 Mail.app. The problem is when I reply to messages on my iPhone, the reply defaults to sending from just one address. I know I can go through a couple of steps to change the sending email address, but in Gmail itself the reply automatically corresponds to the email account the incoming message was sent from.

Is there any way to configure Mail.app on the iPhone to always reply with an account-specific email address?
