I have a problem where a third party needs to redefine how data is queried.

I have table A with child table B. In my application I can grab a parent record A and look at it's colleciton for all child records B.

I have a customer that needs to be able to base the child record query off of another field not associated through a parent child key. They need the ability to add a user id to the query....

Is this possible without having them redo the entire NHibernate mapping... I would like to point them to another DAO that knows how to fetch this data instead of NHibernate automatically loading it... Is this possible?
