title: Return one record from a form data source
body: <p>I have a form with an existing data source. This data source has a one to many relationship to another table that is <strong>not</strong> an existing data source. Even though this second table contains multiple records (one to many), the field in the table that I want is duplicated across all records. Therefore I want to add this second table as a data source, but only return one record from it.</p>
  
  <p>If I add the second table directly, than my form contains a line for each record instead of just one.</p>
