Multiple RadioButton Visibility Binding for a label

I am using a converter

 <Window.Resources>
    <BooleanToVisibilityConverter x:Key="convVisibility"/>
</Window.Resources>

I Have 3 radio buttons:

    <RadioButton Content="PRE" GroupName="Env" Height="16" HorizontalAlignment="Left" Margin="492,167,0,0" Name="radioButton4" VerticalAlignment="Top" />
    <RadioButton Content="POST" GroupName="Env" Height="16" HorizontalAlignment="Left" Margin="558,167,0,0" Name="radioButton5" VerticalAlignment="Top" />
    <RadioButton Content="BOTH" GroupName="Env"  Height="16" HorizontalAlignment="Left" Margin="632,167,0,0" Name="radioButton6" VerticalAlignment="Top" />

I have a label that I am trying to make visible if either radioButton4 or radioButton6 are selected. Currently can get it to work with 4 using this.

   <Label Content="PRE" Visibility="{Binding IsChecked, ElementName=radioButton4, Converter={StaticResource convVisibility}}" Height="28" HorizontalAlignment="Left" Margin="57,262,0,0" Name="label7" VerticalAlignment="Top" />

is there a way to add a second binding to the label or am I SOL, I have tried googling this for the past hour or so and expected it to be something simple, is it doable?

You could use a MultiBinding with a custom converter that OR's the imput values from the bindings to the two RadioButtons.

<Label.Visibility>
    <MultiBinding>
        <MultiBinding.Converter>
            <local:LogicalOrConverter />
        </MultiBinding.Converter>
        <Binding Path="IsChecked" ElementName="radioButton4"/>
        <Binding Path="IsChecked" ElementName="radioButton6"/>
    </MultiBinding>
</Label.Visibility>
