title: Adding date filter In dashboard Metabase
body: <p>I have Native query from My Google Analytics like this:</p>
  
  <pre><code>{
    "ids": "ga:MY_GA_IDs",
    "start-date": "2019-05-01",
    "end-date": "2019-05-31",
    "metrics": "ga:users,ga:newUsers,ga:sessions,ga:bounceRate,ga:pageviewsPerSession,ga:avgSessionDuration,ga:transactionsPerSession,ga:transactions,ga:transactionRevenue",
    "dimensions": "ga:city",
    "sort": "ga:city",
    "filters": "ga:country=~(?i)indonesia",
    "include-empty-rows": false,
    "max-results": 10000
  }
  </code></pre>
  
  <p>I try adding date filter for my dashboard using tag {{date_variable}} But it's not working. How can I adding dynamic date filter to my Dashboard?</p>
