Is it possible to map a many-to-many relationship from a bag in one entity where the cross-reference table also contains additional columns (last updated by/time fields) with NHibernate 1.2GA? I have a table with columns to link to either side of the many-to-many, as well as LastUpdatedBy and LastUpdatedAt columns and need these updated. I doubt this is the first time someone tried to table the issue. Does anyone have any suggestions, or perhaps know for a fact it isn't possible?

Thanks!
