Signing a Multisig (2FA) wallet

[NUFCrichard]

With some of the airdrop alts offering freebies to Bitcoin holders, I was wondering if there is a way to sign/verify my bitcoin address, if I have a 2FA Multisig address?
The addresses I am talking about start with a 3, and so far when I have tried, they don't spit out a code when I try to sign a message.

I know the easy answer is that I could move my coins out of the multisig wallet, then sign from the new address, but is that the only way?
