Have you looked at the reassembly information in README.developer, 
specifically section 2.7.2, "Modifying the pinfo struct" ?  That may do 
the job for you, especially if the messages span multiple TCP segments.  
The preceding section about using tcp_dissect_pdus could work too, but 
it's geared toward simple TCP reassembly.
