Include Files using Wildcard into a folder in Visual Studio

I am using

<ItemGroup>
  <EmbeddedResource Include="..\..\resources\hbm\*.hbm.xml" />
</ItemGroup>

to include a bunch of xml files into my C# project. Works fine.

But, I don't want them in the "root level" of my project, I would rather see them in a subfolder in my project.

For example, this file is included into a Mapping folder in Visual Studio:

<ItemGroup>
  <EmbeddedResource Include="Mapping\User.hbm.xml" />
</ItemGroup>

That's what I want for my *.hbm.xml files.

I can't figure out how to do it and still keep my wildcard *.hbm.xml part and also keep the actual files in a different directory.

I've looked at MSDN's doc on MSBUILD and items, but no luck.
