title: Google Data Studio filter by email and allow all access
body: <p>I'm creating a Google Data Studio dashboard with the filter by email option. It's easy to do it when you want to allow the user to see only one option, for example</p>
  <pre><code>user       region
  alice      A
  bob        F
  charlie    Z
  </code></pre>
  <p>But how can I do to give access to some user to all regions from A to Z? Is there a better way to do it than simply creating 26 rows for every user with this admin access?</p>
  <p>I'd like to avoid creating this table:</p>
  <pre><code>user    region
  admin   A
  admin   B
  admin   C
  ...
  admin   Z
  </code></pre>
  <p>and instead do something similar to this</p>
  <pre><code>user    region
  admin   *
  </code></pre>
