Multiple Stomp servers

Hi, I am trying to configure Stomp input with 3 servers but this doesn't appear to work in ES 7.17.3. I have tried host => "host1", "host2", "host3"
which does not work. Does anyone know how to configure this or is it even possible?
Kind regards,

A stomp input can only connect to one vhost, but you can have multiple stomp inputs.

That's what I figured. Thank you very much.
