HornetQ: Configure the number of consumers

Question

I know that the number of Consumers can be modified with:

@ActivationConfigProperty(propertyName = "maxSession", propertyValue = "X")

where "X" is the number of consumers.

But is there another way of changing them? Because I want to get that number from a File (I read a .properties File, and then I set the number of consumers.

I'm using hornetq 2.2.14.Final with JBoss 5.1.0.GA
