Updating Services in Centrasite to use latest version of Schema

I have a service which refers/uses different schemas. Lets say one of my schema is updated. Then i add a version of the Schema in Centrasite Catalog.
Then i expect the Service to use latest version of Schema with same name. And i don’t want to version the service.

As observed automatically the service is not refering to latest version of Schema and also not seeing an option where i can specify which version to use.

Anybody happen to know how to achieve the same. ?

you might have publish the service as well to centrasite
