For our Android app, we have a number of beta testers signed up via an opt-in link through Google Play. If I do a staged production roll out at 10%, will that include my beta testers or will they just have to be the lucky 10% to get it?

Is there a way that I can publish a version of the app both to beta testers and to 10% as staged roll out at the same time through Google Play?

Basically I want to release to a few specific users (beta testers) as well as to a % of the rest of users, before going to prod at 100%.
