TWO Webcaster X2 devices for 2 youtube events at the same time but with one account

I just bought 2 devices webcaster x2 in order to stream 2 different events at the same time but from the same account.
Is this possible?
Because as I go to “” to link my 2 devices on the same account everything is ok, BUT then how im going to choose which devise plays on which event.
Thank you!!!

This is possible to do, in general the only “special” requirement is that you setup the streams with a single-use stream key, as opposed to a reusable stream key.
