Question: Resolver Execution Order

Hey team, is there a way to execute the parent resolver in parallel with the children resolver?

### What happened?
**Resolver**
```
ParentA:
fields:
ChildA:
resolver: true
ChildB:
resolver: true
```

Currently the execution order is:
- ParentA
- ChildA
- ChildB

I would like the execution order to be:
- ParentA
- ChildA
- ChildB

Is this possible?
### What did you expect?

### Minimal graphql.schema and models to reproduce

### versions
- `go run github.com/99designs/gqlgen version`?
- `go version`?
