Does UCX support nested memory mapping for RDMA operations?

Hello everyone,
I know that it is more than sufficient to register one big memory buffer for RDMA operations.
However, is it still possible to register smaller RDMA regions within an already registered RDMA region?

Yes, it's possible, overlapping RDMA registrations can co exist.

Thank you for the quick response!
