MQTT mulitple topics

Hi,

Is there any way to read many topics using MQTT extension?

When I'm using extension for one single topic eg: topic/device_one/readings/temperature everything works fine, but i also need all readouts using topic: topic/+/readings/+ wich should give me all the topics. But extension lets me map only payload (eg: JSON) but what about multiple topics? Is there any way to retrive this in ThingWorx? Much thanks for any help.
