title: Filter charts with different datasources in a superset dashboard?
body: <p>I'm creating a dashboard with different charts that are the result of SQL queries to different tables in kylin.
  I cant see how to make a filter (of dates for example) that impact in more than one chart.</p>
  
  <p>This filters need to be linked to the table from where the data its taken but is there any other way to do this? Maybe something like an intelligent filter with JS code?</p>
