This is not something that the Play console will do for you.
Some apps do this, since they started beta testing before Google Play beta testing exist, or because they want users to be able to have the beta version and the production version at the same time. One example is Chrome:
Chome
Chrome Beta
If you do this, you have to manage them as two completely separate apps in the Play console. This will work, but:
- it will be more work for you because you'll have to update screenshots, descriptions etc separately
- you can't share in-app products
- Users on the beta can get left behind if you update the prod but not the beta
- it is more work to promote an APK from Beta to Prod
