Smart Assertion on GraphQL Request Step

I was wondering why we can make a Smart Assertion on REST requests but can't make a Smart Assertion on GraphQL Request Step. 

We are currently using REST requests to test GraphQL as suggested and since the Smart Assertion tool is crucial in API testing for us but was wondering if there were any plans to support Smart Assertion in GraphQL requests? Seems like functionality of sending a REST request as a graphQL request is much more feature rich at this point in time.
