title: Change from GCS region settings to multi-region
body: <p>I have been trying to see if we should setup a GCS bucket with <code>region</code> or <code>multi-region</code>. The needs today are regional only. </p>
  
  <p>I am wondering if there is an option to change from <code>region</code> only to <code>multi-region</code> at a later point in time? </p>
  
  <p>This also saves some <code>$</code>'s till we move to <code>multi-region</code> setting. Just having it enabled, doesn't help us much today.</p>
