Custom manifest

I need to add microphone permission to my Daydream app.
Initially I added it to the Mainfest-Daydream xml file (and deleted the AndroidManifest.xml) but If I export to a Android Studio build that change does not seem to be coming in.
I have ended up getting the Android Studio manifest, adding the lines and using it as AndroidManifest.xml in Unity (Deleting the -Daydream specific one) but surely there is a better way I am missing

 

I use the micro permission, too. In my case Unity made that without any problem.

In my file structure Assets/Plugins/Android there are atm three files: AndroidManifest.xml, AndroidManifest-Cardboard.xml and AndroidManifest-Daydream.xml. I added the permission in AndroidManifest.xml and AndroidManifest-Daydream (only thing I changed) and it works.
