Is there any way to get the "any-to-many" side of a many-to-any association? I've got a case where there is a natural many-to-many relationship between two classes, one of which is mapped by the table-per-concrete class strategy. I can get the many-to-any side to work just fine, but how do I get a set on the table-per-concrete class side?

I'm aware of how to do this with the other two strategies, but is it possible with this one?
