title: How to block multiple countries with one expression in google cloud armor?
body: <p>I can block multiple countries in google cloud armor with below rule.</p>
  <p>origin.region_code == &quot;RU&quot; || origin.region_code == &quot;UA&quot;</p>
  <p>But it considers this rule to be having 2 expressions so I can block only 5 couontries per rule and will have to add additional rules to block additional countries.</p>
  <p>Is there a way (like in_origin_regioncode) where I can provide a comma separated list of all countries I want to block in a single expression?</p>
