How to add reference to MicrosoftVisualStudioDesignerInterfaces

I need to create a project and add references to Microsoft.VisualStuidio.Designer.Interfaces, since it does not get listed on the standard reference pane I resort editing the csproj manually adding the references.

<Reference Include=”Microsoft.VisualStudio.Designer.Interfaces, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”>

<SpecificVersion>False</SpecificVersion>

<HintPath>D:\Program Files\Microsoft Visual Studio 8\Common7\IDE\Microsoft.VisualStudio.Designer.Interfaces.DLL</HintPath>

</Reference>

Someone could suggest a better and less hardcore way?
