I have a solution for you...a behavior:

   public static class SelectedItemBehavior
   {
      public static readonly DependencyProperty BindingProperty =
         DependencyProperty.RegisterAttached("Binding", typeof(object), typeof(SelectedItemBehavior),
            new FrameworkPropertyMetadata(new object(),

      }

      public static void SetBinding(FrameworkElement frameworkElement, object value)
      {
         frameworkElement.SetValue(BindingProperty, value);
      }

      private static void SelectedItem_Changed(Object sender, DependencyPropertyChangedEventArgs e)

         ToggleButton toggleButton = (ToggleButton)sender;
         toggleButton.Checked -= ToggleButtonOnChecked;
         toggleButton.IsChecked = e.NewValue?.Equals(toggleButton.DataContext) ?? false;
         toggleButton.Checked += ToggleButtonOnChecked;
      }

      private static void ToggleButtonOnChecked(object sender, RoutedEventArgs e)
      {
         ToggleButton toggleButton = (ToggleButton)sender;
         SetBinding(toggleButton, toggleButton.DataContext);
      }
   }

Then bind as follows:
