Use UseHardlinksIfPossible and SkipUnchangedFiles in Copy task

I'm using your package to include a large set of files (> 500Mb).
Currently all files are copied on each build. Is it possible to add the UseHardLinksIfPossible and SkipUnchangedFiles parameters to the Copy task in the msbuild targets? This will prevent unnecessary copy actions.

Using hardlinks might introduce some issues. Don't you want to add this 500Mb at a later moment in the build/delivery chain?
