Both internal testing and external testing in TestFlight

I have two release trains going in TestFlight:

The App Store version v1.0(0) with bug fixes v1.0(1), v1.0(2), etc.

The next feature version with additional functionalities of the app v1.1(0), v1.1(1), v1.1(2), etc.

Is there any way to have v1.0(x) be for internal testing, and have v1.1(x) be for external testing?

I really need to start external testing the next release of the app in TestFlight, while also bug fixing the current version of the app in TestFlight.

Thanks!
