clarification - possibility to call multiple resolvers (fan out)?

I cannot see if this concept I am missing is feasible, but I have a use case where I need this.

I wish to fan out to multiple resolvers preferable using schemaResolver, and merge the results together, would this be possible with current methods?

My solution now, would be to create a wrapper resolver, that calls and aggregates the results from multiple producers, but i would prefer to have it mapped in the resolver.
