Fluent nhibernate automapping collection - fluent-nhibernate

Question

I am trying to map my collections with FNHib automapping. The problems that I want to solve are:
1) I want all my collections in the project to be mapped via private field. How can I say that globally?
2) Is there any way to automap bidirectional relationship without explicitly overriding each of my entities.
class OrganizationEntity example:
private ISet<> _collectionWarehouse;
public virtual IEnumerable<WarehouseEntity> CollectionWarehouse
{
get{return _collectionWarehouse; }
set{_collectionWarehouse = new HashedSet<WarehouseEntity>((ICollection<WarehouseEntity>)value)}
}
Class WarehouseEntity example:
public virtual OrganizationEntity Organization{get;set;}

You can map your collections to a private field 'globally' with the following convention:
// assumes camel case underscore field (i.e., _mySet)
public class CollectionAccessConvention : ICollectionConvention
{
public void Apply(ICollectionInstance instance) {
instance.Access.CamelCaseField(CamelCasePrefix.Underscore);
}
}
Whenever you want to set a 'global' automap preference in FNH, think conventions. The you use the IAutoOverride on a given class map if you need to.
As far has the set (a HashSet is usually what I really want also) part, the last time I had to do some mapping, I did need to do an override, like:
public class ActivityBaseMap : IAutoMappingOverride<ActivityBase>
{
public void Override(AutoMapping<ActivityBase> m)
{
...
m.HasMany(x => x.Allocations).AsSet().Inverse();
}
}
I do agree that should translate into a convention though, and maybe you can do that these days. Please post if you figure it out.

CODE TO USE A HASHSET as an ICollection =================
public virtual ICollection<WarehouseEntity> Wharehouses
{
get { return _warehouses ?? (_warehouses = new HashSet<WarehouseEntity>()); }
set { _warehouses = value; }
}
private ICollection<WarehouseEntity> _warehouses;
