Cannot use ionic-app-scripts custom config files in command line

[alfabetagama]

What version of the CLI are you using?

2.2.1

Short description of the problem:

Cannot use ionic-app-scripts custom config files path in command line.

If you run

ionic build android --release --prod -s ./config/sass.config.js -r ./config/rollup.config.js

Build fails with error

Error: Unknown platforms: ./config/sass.config.js, ./config/rollup.config.js

What behavior are you expecting?

Ionic command line should accept ionic app scripts parameters

Steps to reproduce:

1. copy config files from \node_modules@ionic\app-scripts\config to config directory
2. run

ionic build android --release --prod -s ./config/sass.config.js -r ./config/rollup.config.js
