So far I have been successful in using CMP/CMR in my application but I'm kinda stuck in a M:M proplem

Entity A is in a M:M relation with entity B. The CMP engin manages the table that breaks this relation but the breaking table only includes the primary keys of entity A and entity B

The prblem is I need to spcify more information in the breaking table, basically I have information that is spcific for every (A,B) pair

Is there any way I can take advantage of the CMP engine to mange such relation or do I have to break my M:M relation to 2 1:M relation and deal with the two relations and extra entity

Thanks
