Save Plugins outside Assets/Plugins

Normally when adding plugins for Android and iOS you have to add them to the directory.

Assets / Plugins / iOS

Assets / Plugins / Android

I am now looking for a way to save these plugins in a different way like:

Assets / MyLibrary / Plugins

The problem appears on build. If I change the structure, the plugins won't be available inside the builded package. Does somebody know if there is a way you can change the structure so Unity still can work with them?
