Make BuildPipeline.BuildAssetBundles accept full path instead of project relative ?

From https://docs.unity3d.com/ScriptReference/BuildPipeline.BuildAssetBundles.html

The method :

public static AssetBundleManifest BuildAssetBundles(string outputPath, BuildAssetBundleOptions assetBundleOptions, BuildTarget targetPlatform);

And :
The outputPath is a path to a folder somewhere within the project folder where the built bundles will be saved (eg, "Assets/MyBundleFolder"). The folder will not be created automatically and the function will simply fail if it doesn't already exist.

This is very bad, I want to save my assetbundle from one project to another, this limits the functionality...
