How to make multiple buttons with different backgrounds from one template in Expression Blend 4

Question

I made a simple button template from the rectangle with "Make into control../Button" command. Now, I need several buttons from that template but each button must have different background image. I tried to do that in Blend4 but when I change the button background, button holds to a template background (or none, whichever is set in template), ignoring the image I have set for that specific button. Button Template:

btnMenu (No brush)
    -rectangle (No brush)
    -[ContentPresenter] (some text)

I apreciate any advice.

Style:

<Style x:Key="btnStyleMenuHome" TargetType="Button">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Grid x:Name="btnMenu" Width="90" Height="70" Margin="0" VerticalAlignment="Center" HorizontalAlignment="Center">
                            <Grid.Background>
                                <ImageBrush Stretch="None"/>
                            </Grid.Background>
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CommonStates">
