User Management - Add 'App Tester Groups'

App user management currently has these fields for adding users to a project:
• Available to Select Users
• Available to Select Groups
• App Testers

Recently I came across a situation where I wanted to add entire groups that can test an app.

The client was in the group we created for the project and that group was added to "Available to Select Groups" field.

It did not work, I believe, because the Android app was technically a test build, and; both the "Available to Select Users" and the "Available to Select Groups" fields are for production level builds.

Would you consider adding the ability to either 1) add groups added to 'App Testers' field or 2) Add another field, "App Tester Groups" to add groups in it's own place?

Thanks for the consideration.
