Build Assetbundles outside project?

In the documentation for BuildPipeline.BuildAssetBundles the "outputPath" parameter specifies the location in the project that you want the Assets to build to.

For example, "Assets/ABs" puts them all into the "ABs" folder in the root of your project.

I need these AssetBundles to build to a folder outside the project, like my desktop. Is this possible?

Thanks!
