[Discuss-gnuradio] Passing a message from one block to other

Suppose I have two gnuradio blocks called gr_ACQUISITION and gr_TRACKING where, gr_TRACKING is dependent upon some result derived from gr_ACQ block. Is it possible to pass certain messages to gr_TRACK in order to change its state while the flowgraph is running? One way to do is to have an output line in gr_ACQUISITION that carries this info to the block gr_TRACKING but this doesn't seem like an attractive option to me.
