Role based access control to WSO Message Broker Hierarchical Topic - jms

Question

I've recently started experimenting with a Message exchange between WSO2 ESB's via WSO2's MB for a requirement. Created a JMS sender Proxy Service which concatenates endpoint URL based on SOAP Input (used Header property and defaultEndpoint).
On Message Broker:
Have set up a Hierarchical topic as
Root|
Node1
Node2
With 3 users and their specific roles as Root, Node1, Node2. Requirement is Node 1 should be able to subscribe for both Node 1 and Root, Similarly for Node2, Only Node2 and Root.
The problem is When creating a proxy service subscriber can only set it to subscribe one Node only (Root or Node1 or Node2). Tried setting destination as Root.# but then All Nodes are subscribed (even when Node USer is not set to Subscribe the other based on Role based Topic access). Following is the code for subscriber
enter code here
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="Subscriber_Node2"
transports="jms"
statistics="disable"

jndi.properties:
connectionfactory.Node1TopicConnectionFactory = amqp://Node1:Node1#clientID/carbon?
brokerlist='tcp://localhost:5680'
connectionfactory.Node2TopicConnectionFactory = amqp://Node2:Node2#clientID/carbon?
brokerlist='tcp://localhost:5680'
connectionfactory.RootTopicConnectionFactory = amqp://Root1:Root1#clientID/carbon?
brokerlist='tcp://localhost:5680'
topic.Root = Root
topic.Root.Node1 = Root.Node1
topic.Root.Node2 = Root.Node2
Is there a way a Subscriber can subscribe to Multiple Topics in a hierrarchy and its access be controlled by User and Role?
