Wpf 从现有样式继承并向衍生样式添加新形状

我有基本样式

playbuttonstyle

和继承的

pausebuttonstyle

，这是基于第一个样式的。如何将形状添加到派生形状？我想添加两个矩形，使其看起来像暂停按钮（混合或VS）

派生：

<Style x:Key="PauseButtonStyleInherited" BasedOn="{StaticResource PlayButtonsStyle}" TargetType="{x:Type Button}" >

基本：

<Style x:Key="PlayButtonsStyle" TargetType="{x:Type Button}">
    <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
    <Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/>
    <Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
    <Setter Property="HorizontalContentAlignment" Value="Center"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Padding" Value="1"/>
    <Setter Property="Width" Value="40"/>

我认为你做不到。我认为您需要使用派生样式中的其他形状重新定义控件模板
