How to mirror MacBook Pro to 2 Apple TVs

Hello,

Is it supported to be able to mirror my MacBook to two TVs, each of which have an AppleTV connected? I've been able to mirror to one, or the other, so far, but not both at the same time.

The purpose of this is for a company town hall, where I want to present recorded material and slides on 2 Tv's in our conference room.

Any help is appreciated,

Thank you,

Mike
