Non-root directory Ionic project possible?

Appflow
#1

Question about directory structure for ionic1 deploy. Our repo is structured like this

root/
 mobile/ # the ionic1 project
    www/
 server/
 …config files, etc

Is there a way to let Ionic deploy/build processes know to look at mobile/ rather than root/? Maybe an undocumented root/.ionicrc or some prop in root/ionic.config.json? (edited)

Looks like https://ionicframework.com/docs/developer-resources/app-scripts/#custom-project-structure could help, but simply including config: {ionic_root_dir: "mobile"} in package.json doesn’t work.
