title: multiple Azure VM deployment in selective zone
body: <p>I'm trying to deploy two VMs in to selective availability zones in my Azure subscription. I was referring the code below to to get an idea how zone works with Azure VM deployment.</p>
  
  <p><code>"zones": "[split(string(add(mod(copyIndex(),3),1)), ',')]"</code></p>
  
  <p>Now I am trying to parameterize or introduce variable in some way so that I can have two different zone explicitly defined for two VMs and but works with any zone number between 1 to 3. </p>
  
  <p>Does anyone know how I would achieve this?</p>
