title: Use two/multiple selected directories from custom page in Files section
body: <p>I need create custom page of two destination.</p>
  
  <p>I've done:</p>
  
  <pre class="lang-pascal prettyprint-override"><code>#define MyAppName "TESTPROG"
  [Setup]
  
  AppName={#MyAppName}
  DefaultDirName=C:\test\{#MyAppName}
  DefaultGroupName={#MyAppName}
  
  [Code]
  var
    Page: TInputDirWizardPage;
    DataDir: String;
  
  procedure InitializeWizard;
  begin
    Page := CreateInputDirPage(wpWelcome,
      'Select Personal Data Location', 'Where should personal data files be stored?',
      'Personal data files will be stored in the following folder.'#13#10#13#10 +
      'To continue, click Next. ' +
        'If you would like to select a different folder, click Browse.',
      False, 'New Folder');
  
    Page.Add('Local APP');
    Page.Add('Local Storage');
  
    Page.Values[0] := ('C:\My Program');
    Page.Values[1] := ('D:\My Program');
  
    DataDir := Page.Values[0]; 
  end;
  </code></pre>
  
  <p>I need to know how and where I set DefaultDirName with <code>Page.Values[0]</code> and <code>Page.Values[1]</code></p>
  
  <p>I need it because some part of my files will be in a folder and others in other folder.</p>
  
  <p>For example:</p>
  
  <pre><code>[Files]
  Source: C:\TEST\DLL1.bat; DestDir: Page.Values[0]\sys1;
  Source: C:\TEST\DLL2.bat; DestDir: Page.Values[1]\sys2;
  </code></pre>
