How to implement Oauth2 auth for different hosts on one kong instance?

There any possibilities to configure oauth2 for differnet hosts?
for example: /api1
and: /api1

oauth2 plugin configured on routes, with gloabal_credentials to provide one auth point for all apis.
So when I do request to dev I got a valid token for both -dev and qa.
Can I configure it to have independent code? (code from dev not valid on qa, qa not valid for dev) ?

Question not valid for now.
For this purposes can be used ACL plugin, and divide consumers by different groups (for api1, api2)
