Add more than one authenticator for 2FA

I have more than one phone (no I'm not a drug dealer or a terrorist) and whenever possible I register the 2FA seed in an authenticator app on each phone. Some sites make this easy, for example Amazon allows you to register multiple authenticators with different seeds while LastPass will allow you to re-display the QR code so that another app can be added at a later date.

Can A&A allow either of these options? At the moment the workaround is to turn off 2FA then turn it on again and register all the authenticators at the same time. This means that if I lose a phone or have to reset a phone I can still get into my account using the other one then reset any security factors that may have been compromised.
