Third or fourth factor authc?

Is it possible to create a user experience where someone is required to enter RSA AND Google Authenticator. It seems like if I enable multiple factors, the user gets to choose one. What if I wanted him to enter one after another (Dr Evil laugh). Is this do-able ?

the first time I setup the mfa on the account it seemed like it prompted me for all factors sequentially, but not after that. It just lets me choose a second factor, provide creds, and I am in.

I believe you can do this with Factor Sequencing
