How to save sound file in Voltbuilder

I need to save a sound fiile in specifcs paths to onesignal push use to use in notification push, is that a way to do this?

the paths is:
iOS: /platforms/ios/project-name.xcodeproj
android : /locales/android/raw/

docs: Notification Sounds

VoltBuilder creates these directories on the fly, so the method they detail is not going to work.

We have not used this plugin ourselves, so we don’t know the answer to this. However, I know people are using this with VoltBuilder. You could post this question to the VoltBuilder forum - hopefully one of the people using this plugin will know the answer
