WIX ComponentGroup subdirectories

Question

I would like to install my application into the following directory structure:

MyCompany/
    MyApp/
        assembly1.dll
        assembly2.dll
        assembly3.dll
        ...
        plugins/
            plugin1.dll
            plugin2.dll

For this, I defined the following folders:

<Directory Id="TARGETDIR" Name="SourceDir">
    <Directory Id="ProgramFilesFolder">
        <Directory Id="CompanyFolder" Name="MyCompanyName">
            <Directory Id="INSTALLFOLDER" Name="MyProduct">
                <Directory Id="PLUGINS" Name="plugins">
                    <Directory Id="DATABASE_PLUGINS" Name="db" />
                </Directory>
            </Directory>
        </Directory>
    </Directory>
</Directory>

Now I have defined 1 feature with a reference to a component group. This component group has a property "Directory" pointing to "INSTALLFOLDER". But when I now declare a component in the component group that has also a "Directory"-property (pointing to DATABASE_PLUGINS), VS won't let me build the setup.

<ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER">
    <Component Id="DB.Connector.Extension.Plugins.SqlCe" Directory="DATABASE_PLUGINS" Guid="{ae87be28-b0c9-4b3e-915f-2b4bf9965c99}">
        <File Source="$(var.DB.Connector.Extension.Plugins.SqlCe.TargetDir)DB.Connector.Extension.Plugins.SqlCe.dll" KeyPath="yes" />
    </Component>
</ComponentGroup>

How can I achieve that the setup creates a subdirectory inside my main install directory and puts declared files into it?
