Setting Parent in Route and Query with References

I have a route “/about”, that has an

subRoutes

array of references to other routes. I’ve added “/about/team” to this array.
So now “/about” knows about the sub pages due to

subRoutes

but the sub pages them selves doesn’t know about their “parent”.
I think I need to set

parent

in the route, and query with

references(^._id)

but I feel that I miss another argument to specify that the reference only is relevant if it’s within

subRoutes

. It would otherwise give me all references, that aren’t from

subRoutes

.
Or what?

Is this what I am looking for?
