VS2010 Deployment package MSBUILD

Question

The VS2010 Deployment package feature creates the package with a directory structure like:

Package\Archive\Content\C_C\Sources\Website1\Web\obj\Debug\Package\PackageTmp

I want to have the contents of the last PackageTmp in the root and not the whole directory structure. What is the best way to do this, create a custom task which copies it to the root?
