Thanks for the reply @arunpatidar
Let me reframe my requirement here. I have defined Styles on Component A Policy and I want to reuse this Component A Styles on Component B in addition to the Component B Specific Styles.
Requirement here is to reuse already defined styles of Component A on Component B and Components B should also have its own policy.
The above solution which you provided will only inherit component A policy on component B.
The policy combination is not supported. you can't refer two policies at the same time.
