Can router forward certain keyexp to another router?

[jpeeee]

We use zenoh between 2 devices.
We want to have a pair of router on each device to create 2 zenoh networks.
We would like to do this without the applications using zenoh to know which network they use.

Is it possible to configure one router to send a selection of keyexpr to the router on the other device and forward the remaining keyexpr to the other router on the same device?

That way we could assign specific messages to specific router and change the selection without making code changes and not the application knowing which network they use.
