Inno Setupでカスタムページのラジオコントロールを2つの異なるグループにするにはどうすればよいですか？

私のアプリケーションには、次の設定ウィンドウがあります。

私は、このウィンドウをInno SetupInstallerで可能な限り複製することを考えました。

現時点では、次のコードがあります。

procedure pageAutoBackup_Create;
var
    { Controls }
    pageAutoBackup: TWizardPage;
    btnSelectBackupFolder: TNewButton;
    textBackupFolder: TNewEdit;

そして、これはそれがどのように見えるかです：

私の最初の質問は：

私には2つの無線グループがあります。

• バックアップするもの
• バックアップする方法

現在、私のラジオコントロールは1つの大きなグループとして機能しています。2つの異なるラジオグループモードにするにはどうすればよいですか？
